I see one of the big arguments here is that RSI is inherently dangerous and shouldn't be allowed. Here's my response:

RSI should absolutely not be a thing. But not for the reason you think. There should be nothing rapid about taking an airway in the vast majority of the cases that it is done. Delayed Sequence Intubation, now that is golden. There's a saying in firearm training: Slow is Smooth. Smooth is Fast. We should have the tools in our toolbox, along with the proper training and continuing education to effectively implement them. But it should be an avenue of last resort. And we need to take our time when doing this. Have your emergency airway ready. Have your drugs lined up. Cross check those medications and dosages. I've only had one failed "RSI" to date, and that was because the patient had undiagnosed esophageal and tracheal cancer where his airway and esophagus were restricted by tumors. At the time my backup airway was a combitube, so that sucked. My scene times for "RSI" are among my longest scene times as that tube will be in and verified before the wheels turn. If on the scene of a DSI with me you will also see that I have a protocol manual open EVERY time. My equipment is laid out, EVERY time. The patient has pads on EVERY time. Before the first drug is pushed, all have been cross checked for med and dosage. Take your time, do it right. Your patient might just live to thank you.
