This is Ba Sing Se levels of delusion for some people.
For example the Rayshard brooks shooting. Why was a gun needed to wake a man sleeping in a car. Why are guns needed to hand out speeding tickets.
I get that guns are needed if a bank is being robbed. But this is glorified customer service work. Imagine your car breaks down and the AAA guy who came to fix it had a gun. Like y tho?
Perhaps it's because at least some of the people they stop, for speeding or other possible offences, won't take kindly to being stopped and in many parts of the USA, those in the vehicle may be permitted to carry guns of their own...
Glorified customer service work? Far from it
Isn't the issue with laws that those breaking them don't usually care about laws? I'm sure you have laws in place against murder, and murder still happens. "But there's a law against burglary, why would you want additional protection and have a strong door" isn't a good argument.
There are good arguments (and the whole issue is a good gun control argument in general), but that really isn't one.
Sure, there are also some people who violate gun laws. But those people could be a threat to everyone, not just cops, yet surely we wouldn’t justify everyone to preemptively have their guns drawn in all human interactions.
