I agre with much you have said; but alot of crime is moving to small town America because the perps know there is not the manpower to counter them. MS13 types and the meth cookers set up out in the country. Less “interference” there.
I don't think that's the problem. Virtually every county, and I'm guessing every city over 75,000 has it's own flavor of SWAT, SRT, or whatever moniker you want to hang on it. That doesn't count the state police entities, game warden SRTs (yes, there are such things), Department of Agriculture, DEA, US Marshals, FBI, ATFE, and numerous other federal entities. The problem is not a shortage of manpower or equipment; it's a lack of willingness to go after the criminals that might actually shoot back.
