So, regarding police performance in this Uvalde school shooting

• Yeah, sending handgun-armed patrolmen through a door to a room with an assailant with an AR, believed body armor, and if he wrote all that manifesto about equipment nope, wrong guy presumably enough tactical sense to focus on the single entrance to the room presents such obviously low odds of success I can see competent judgement not choosing it
• The officers on site had no body armor, no flashbang(-equivalents) to soften up an assault or smoke to mask it, and no long arms, which also means they had no ability to shoot the lock out of a door (and presumably didn’t have a battering ram with them)
• In that situation, “confine and wait for specialized units” would in fact be – reasonably! – doctrine
• My mind can spin up ideas of i.e. covering one of those wheeled carts with textbooks and pushing it ahead as a bullet sponge, but that’s after-the-fact, if they even got the door open I imagine the only practical immediate intervention would be to rush the room with 5 or more officers with the understanding 2 or 3 will be casualties
• This would require very high officer morale and unit cohesion
• I actually think the cop side might be correct in raising the issue of anti-police public sentiment, as a force degrading morale
• “We will fall short of your expectations until your opinion of us improves” is a weird angle to try and work through
• Historically America has at several times and places seen a less prominent role for the police.
• Their functions are replaced with lynch law, mob rule, mercenary forces, gangs, and organized crime
