I live in the UK. If three sleazy-looking lunatics showed themselves walking around like this they’d rapidly find themselves confronting armed police and either shot or handcuffed and taken into custody. Rightly so.
Who needs armed imbeciles roaming the streets with military grade armament?

It makes America a dangerous third-world country!

What are these guys up to? Who are they trying to intimidate? What are they so afraid of?
