You could, but SWAT units use military gear.
I thought you were opposed to that ?
But what about a simple domestic disturbance, where the husband is drunk and beating on his wife ?
Have you ever tried to talk to a violent drunk ?
The only thing you can do is forcefully remove them, until they've slept it off.
This is just a proposal so far, and hasn't been voted on yet.
If it does go through, I can see all the affluent whites moving to privately protected neighborhoods, while blacks are left in the disadvantaged, unprotected areas, and the situation will get even worse, not better.
And if enough cities decide to follow suit, I can see fear, and need for protection, driving white voters to choose voting for D Trump again this November, as the self-billed 'law and order' candidate, and the world is stuck with D Trump another 4 years.
( hope he's too stupid to take advantage of the situation, in that case )
