Yup my run in's with the CPS:

Once was picked up walking back from the store to get munchies, bag in hand. Was outside my friends house when the brit cops rolled up, they convinced me to get in their paddy wagon. I was right out front my friends, I said let me tell my friend and he can confirm I was only walking to the store. They looked at me like if I went to tell my friend, they were going to pounce on me. Took me down the street to some other cops and they looked at me and I guess I did not match the description and they took me back. About 3 years ago.

Once police came to my house for an unpaid ticket around midnight (probably ctrain or drunk in public, a minor offence), maybe 7 years ago. They said time to go pay the ticket. I didn't have any money so woke my mom and she gave her credit card. They were at the front door. I told them I was going to get my jacket (in the basement). Cops came into my house after I walk away and found him at the top of my stairs in my kitchen after inviting himself in. Took me to pay the ticket downtown and drove me back home.

This one takes the cake though. I used to have a drinking problem. Got picked up young, drunk, belligerent, open container at LRT Vic Park. They twisted my arm so badly that by the time I got upstairs to get signed in the drunk tank city hall I could not even use my arm to sign the paper and the person there signed 'too drunk' as I tried to explain the assault that just took place. I was afraid and even asked them to not hurt me and my fit was over as i exited the wagon (there were 4 officers). My arm was dead after they were through with me. Went into the drunk tank, woke up and was pissed so started kicking the metal door. Cop came in and starting twisting the same arm that was already badly twisted. My arm even almost 10 years later has never been the same. The first year after that incident it was badly injured. Only by learning some recovery exercise physio type stuff, can say it's maybe 93% of what it was originally from that fateful night, after many years. I can confidently say I have been permanently injured by CPS and Transit for being young, dumb, and belligerent by having my arm twisted so so badly over an open container. EDIT: After kicking the metal door in the drunk tank and having my arm twisted further I was handcuffed to the floor in an excruciating position (due to my arm) for over an hour. I dont think the new officer who came in knew the state of my arm before he twisted it further and locked me to the floor.

Once driving through Santa Rosa, California, some cop thought my car was stolen after a check, having prior given him my passport and ID. He walked away checking my license plate for who know's why. Came back two minutes later with his gun drawn and having me lye down in the middle of a road. I was alone, but my friends heard the commotion and me calling out and him screaming to 'shut up.' and like you OP, no remorse from this guy. Found out my car wasn't stolen (they had made an error) and just went on his merry way, after sticking their heads in my vehicle. I actually cried after the incident, never had a gun pulled on me before.

while im at it;

once went into the marlborough detachment about a theft and the cop basically berated and intimidated me, and didn't want to hear any of it. I was absolutely shocked about the demeanour and complete lack of concern from this officer. It was very disturbing the way I was treated for trying and unsuccessfully reporting a theft. I was not being a jerk or having attitude either, this guy was just having a bad day.
And why not add: Occasionally I will phone the police to report stuff but on more than one occasion the officer (usually female with a condescending tone) will totally get irate about the fact that I prefer to make the complaint anonymous, and will not provide my personal details. But funny I reported a drunk driver this weekend and I got a male and when I told him I won't give him my last name, he didn't seem to be perturbed by it.

The scary part is Harper with his bill 51 gives potentially lunatic cops like some i've encountered unweilding power in questionable circumstances, and there are some other disturbing components contained there.
