Both tactics are valid and useful in different ways.
Personally, I think it's past time to start shooting the bastards. That's one reason I don't get particularly bent out of shape when one of the mobile tax collectors has a not-so-friendly encounters with a victim of modern-day highway robbery. I'm actually genuinely surprised we don't see more examples of those following Carl Drega's footsteps more often. Unfortunately, enough people are satisfied with bread and circuses, so my viewpoint is not as popular as I expect it to someday be, though it's going more against the state (all levels) every day.
Ahh...yes both have their time and place... But I was thinking more on the lines of intel denial across the board rather than a cam here and there.... for starters.
