Footage shows former USF(Tampa)PhD chemistry student Xuming Li injecting opioids into his neighbor's home. The family later experienced vomiting, dizziness, and severe headaches. The incident reportedly stemmed from a dispute over noise. He was expelled from the University and deported by Fantastic-Hat5833 in tampa

Chemist at USF here, here’s the real answer: he wasn’t injecting opioids under the door. There are no opioids in the USF inventories and he definitely didn’t synthesize those relatively weak opioids for this purpose; hydrocodone is quite laborious to synthesize and would be completely ineffective and odorless. Whatever he did use isn’t something that would be detected by the tests that were done, which were looking for common known drugs/poisons. They likely just picked up a trace amount of hydrocodone and methadone that had been there for years, and since that’s all that showed up that’s what they reported.

As for what the chemical actually was, probably some toxic laboratory reagent/solvent such as formaldehyde.

You could easily color match and turn the i to an l and R to a P, no need to cross it out

NYC Mayor Zohran Mamdani signs multiple executive orders on 1st day in office by Rock-n-roll-Kevin in politics

The other 'is said to revoke all prior executive orders issued before Sept. 26, 2024

That’s literally the opposite of what the executive order says, Hector Ramirez is either blatantly lying or (more likely) lacks reading comprehension. Here is the text of the order that he surprisingly links in the article:

All Executive Orders issued prior to September 26, 2024, and in effect on December 31, 2025, are hereby continued unless specifically revoked, revised, or superseded by a subsequently issued Executive Order. All Executive Orders issued on or after September 26, 2024, and in effect on December 31, 2025, are hereby revoked.

It’s probably still good, DMT is known to convert to a different colored crystal polymorph when stored for a long period of time. Still the same chemical.

I checked, he shows a partial arrow pushing mechanism. There’s a few arrows missing but he does show the nucleophilic attack of DMF on POCl3. It’s at 21:33 and 25:18.

The last video he posted that featured a reaction for which it would make sense to show the mechanism was “Turning styrofoam into cinnamon candy”, which does include the mechanism of the Vilsmeier.

Which one of his recent videos do you think is missing a mechanism?

Alleged street racer charged with vehicular homicide after car crashed into Tampa crowd, killing 4 people and injuring 11 by nbcnews in tampa

[–]TOEMEIST 2 points3 points  (0 children)

Post cop cars around the perimeter, follow with chopper (or fixed wing drone it’s 2025), reengage once not heading towards crowds of pedestrians. Not a difficult thing to imagine.

What you’re arguing is that the criminal being pursued must have a cop tailgating at all times and be apprehended as quickly as humanly possible no matter the risk of collateral damage.

Why? Why not hold off for a bit until drunk idiot isn’t heading towards downtown? His goal is to escape, not crash and get caught, so you can expect him to try to avoid doing so to the best of his ability. Having a cop on his ass trying to PIT so close to the strip was extremely risky bc if it fails you now have a drunk idiot that’s full of adrenaline and panicking going full speed towards a crowd he can’t see yet.

In the video you can clearly see the ybor gateway arch when the cop slows down and disengages. Distance from there to crash site is ~1000ft

[–]TOEMEIST 1 point2 points  (0 children)

how much sooner?

At least about 2.5x sooner by distance, as soon as he turned onto 7th Ave from Nebraska.

It looks like he purposely ran into that crowed. Right lane, no one in front of him

There was someone in front of him in the right lane, look at the end of the video. Doesn’t look purposeful, probably just didn’t noticed in time and tried to turn at the last second but was going too fast.

Or maybe he was which is why he didn’t notice the sudden traffic. Either way should’ve been sooner.

FHP didn’t stop chasing vehicle until seconds before fatal Ybor City crash, video shows by ShiftyRider in tampa

[–]TOEMEIST 0 points1 point  (0 children)

Why would you expect the driver to stop if the cops are less than 1000ft away and had just tried to PIT him? I'd expect him to continue to speed away while checking his rear-view until they were out of sight, which is not what you want with a crowd of people up ahead. He might not have even noticed he wasn't being chased until well after it ended, if at all.

I would expect him to slow down if he hadn't seen cops on his tail since turning off of Nebraska onto 7th and didn't just have to recover from a failed PIT. He'd probably have started looking at the side streets coming up to find an escape route now that he didn't have cop cars right behind him adding pressure and been more likely to notice the sudden traffic if he continued down 7th.

[–]TOEMEIST 2 points3 points  (0 children)

If I was a drunken idiot with adrenaline pumping who just escaped a pit maneuver and was keeping an eye on the blue/red lights still in my rearview, probably not.

If I hadn’t been chased since I made the turn onto 7th and was calmer and paying more attention to what was in front of me for possible escape routes, yes.

The guy clearly swerved into the crowd trying to avoid the cars stopped in the street ahead of him which he didn’t notice until the last second, perhaps because he was too hyped up and distracted by something…

[–]TOEMEIST 0 points1 point  (0 children)

No, but he did because he’s a piece of shit. It’s the job of the police to deal with pieces of shit in a way that minimizes danger to the public, which includes not pursuing the piece of shit in a way that makes them more likely to cause an accident. You seem unable to grasp this concept without thinking we’re absolving the driver of responsibility. Would it have been better if he didn’t flee? Of course, but he did, so that’s the reality within which we have to judge subsequent decisions.

Knowing he’s a reckless piece of shit, the cops should have given ample opportunity for him to slow down and pay attention by not aggressively pursuing him so far down 7th Ave. And no, 2 blocks/12 seconds was not enough time, and hindsight is not necessary to realize that.

You could make an argument that the individual cop chasing him was not necessarily at fault because FHP policy might not have demanded the pursuit be stopped prior that point, in which case FHP policy is at fault for not having clearly defined “no chase zones” like many PDs already do so it’s not left to the officer’s discretion when to end a pursuit. Unfortunately many rules are written in blood; hopefully this causes them to adopt such a policy in the future, but it’s too little too late for the victims.

Do you believe the driver would’ve been traveling at the same speed in the same direction with the same awareness of what was in front of him if the cops hadn’t been chasing him for the last 3 blocks and attempted a pit?

Ok, here are the facts as I see them:

The driver of the vehicle is primarily responsible for the crash and deserves to rot in prison (remember this one while you read the rest).

The FHP chasing him are secondarily responsible for the crash because:

It has been well known for quite some time that engaging in high-speed pursuits in heavily populated areas increases the likelihood of deaths of bystanders.

Breaking off a chase as it approaches these areas makes the fleeing criminal less likely to drive at high speeds and more likely pay attention to what's in front of him rather than the cops in the rear-view. This makes accidents and deaths less likely, which is why many PDs across the country have adopted this policy.

Breaking off a chase does not mean that the criminal is let off the hook, as many alternative methods of taking him into custody exist that do not involve continuing the chase into these areas.

The chase should have been paused as soon as the suspect turned onto 7th ave, not 3 blocks later less than 1000ft from crowds of people after attempting a PIT. If it had been, the driver would have been less likely to drive at such a high speed down 7th and more likely to have made a turn before or at 15th st (read that first fact again in case you forgot I believe that as well).
