The 101st had M203 grenade launchers, AT4 anti armor rockets, and lots of other goodies, including artillery and air support (rotary wing). Few departments woudl have any need for that stuff, but any did, it would be border cities, like El Paso.
Although guarding the border and preventing invasions, by foreign governments or other foreign entitites, is really the job of the Federal Government, per Article IV Section 4 of the Constitution. However, Article I, Section 10, does allow states to "engage in War", if actually invaded or in imminent danger that will not admit delay. Seems to fit the situation from Brownsville to San Diego. But that's a job for the Militia including it's organized components the National Guard and State Guard, not city cops.
Number one: I said that no federal dollars with their nasty strings should be attached to up arming ANY local law enforcement.
Number Two: I am well qualified to understand the differences between the armament of an infantry unit vs ar15’s but thanks for the heads up anyway.
Number Three: It should not be controversial within the ranks of liberty loving small government types to express a distrust of a large, powerful well funded domestic police force. That should NOT be a controversial statement.
The 2nd Amendment, if properly exercised would take care of the need for a professionally armed, full time quasi military police force. I just like the local, city, county, state and federal government to always have that gnawing sense of doubt... “Can we take them?”
