Englands bobbies dont carry,or none used to. In this scenario, since its people can't have guns,unless under heavy approval,hoop jumping, and money spent, it's perceived as an even ground scenario.
No bobbies going to kill a few people by hand, with a public fighting back.
However, our guys do carry, so do we. Imagine if they opened fire on the public? The blm and other scenarios come to mind real quick,when we can't carry. Worse,when it happens.
The black panthers did the same in san frans city hall. No shots were fired, but it put certain things front and center. No one liked it, but when our government ignores us, over or under steps its bounds or resposibilities, the people wont wait at times to vote em out, but remind them who's in charge.
