That's what you need Bobbies for

That those guys with a wissle that will stay away from the Machete Street Samurai on his last mission for some time, but make sure by shouting and presence that the people do not run, panic and understand safe zones. 

Armed Police needs to be more flexible in movement by even Tiny Bird Helicopters, in quantity you'll need more community Police, The Bobby. 

PS: That and only that is a Bobby. Selected by social skills in a passive uniform.

That is a Police Officer with a Bobby hat (which is actually a helmet) 

None is armed Police.
