That would be the role of countersniper indeed. Albeit I'll suggest that all you state would be well used in a non urban environment such as a wooded area or jungle where all things human stand out like a neon sign to a good stalker.

But such methods has serious holes in the Asphalt Jungle involved here. I think if deployed in the numbers required to cover the DC/VA/MD area they'd be shooting each other and getting the right one would be analogious of winning the lotto.

Good points though, Stay Safe !!
