Here are the problems:
No knock warrants - unless there is credible evidence that someone inside the dwelling is in immediate danger, I am absolutely okay with eliminating these. It should be noted that Waco started with essentially a no-knock warrant (by a no-brains agency).
Chokeholds - Completely good with that (eliminating them) if a suspect is in custody and secured (cuffed). Standard policy should be - and it usually is - to get them down, get them cuffed, and get them on their feet (as long as there isn't an injury preventing that). In a fight, not sure.
More hand-to-hand combat training - Good except police are already limited in what they can do in a fight. I don't know how these rules slide based on situation but I think there are already restrictions. It's based on not injuring the suspect. As long as the officers have the numerical advantage this is probably fine. That said, I don't like two average-sized officers' chances against someone the size of Dexter Lawrence. Point being this is probably complicated, but more training is always better. So okay.
Liability protection - I don't like the idea that a cop can be sued for doing his job. Probably do the protection in the form of insurance provided by the municipality that employs the cop.
Murder charges for any officer who kills another human in custody - will have to be based on preponderance of the evidence. Cannot make that carte blanche. What if the suspect has a gun they snuck in somehow? So this cannot be automatic.
Elimination of 12 hour shifts - Sounds good to me
More funding - actually I would do something like the Albaqueque (sp?) plan and look into a different department for calls that are not actual law breakers. Homeless, animal control, mental health, non-violent drug offenses, all the other weird shit that officers can get into - move that to another department. Give them badges and guns if needed (along with the requisite training) but make them a separate department all the way up to the Mayor or City Council. This adds accountability too, since one fear some cops have is that their life may depend on the actions of another cop. So if they 'rat out' another cop..........
The idea is to move the focus away from the stupid crap and back into protecting the people from, well, honest-to-god bad guys.
Add - resource officers are for threats to the safety of students. That's it. They are not to discipline students for stupid crap. That is on the administration.
