As do I. But the way for that is for sherrif, or police, to call out the posse, the same folks who constitute the militia. Put a trained and practiced shooter on the roof of shopping malls and other likely targets. Put a cop, although you might have to settle for a reserve officer or even a National Guardsman in some cases. That's the way these guys will be caught, it's also what the Israelies do, they've also taken to arming kids too young to be called into military service, and letting them man checkpoints. Such an action would also cut down on "normal crime too of course, whereas using only police will divert them from investigating or responding to such more normal crimes and probably lead to an increase in such crimes.
However in these oh so "sensitive" times, using armed civilians is the last thing those in government, at all levels, are likely to do, at least in the oh so sohpisticated area around DC. If it were out here in fly over country, especially outside the major urban areas, there would already be posses out beating the bushes and defending the vulnerable places.
