SH: “What do you mean, ‘shock and awe’?”
Bob: “I’ll call for reinforcements. An additional one, two, three or even four squad cars will all descend on the guy, and as many or more cops will surround him all telling him to identify himself and tell us why he’s taking the photos. If we intimidate him, he may tell. If he becomes angry and objects violently, we can arrest him for disorderly conduct and get his ID that way. If he stays cool and does not give us grounds to arrest him, then there’s little to do, but we’ve made our point. Do you think he’ll photograph a high-value target again?
