Greetings from Fairfax County, Virginia.
I must take exception to your choice of words, here. That fellow you have shooting up cars on your highways may be many things (assailant, murderer, terrorist ...) but he is not a sniper. A sniper is a specialist soldier whose job is to kill specific high-value materiel targets and enemy personnel in and around a battlefield, for the purpose of more quickly and efficiently winning wars. His purpose, ultimately, is to win a war while preserving the lives of his comrades and preventing unnecessary collateral damage to civilians.
Convicted Terrorist John Allen Muhammad is not a sniper.
Accused Terrorist Lee Boyd Malvo is not a sniper.
The person shooting up buildings, cars, and people near I270 is not a sniper.
I hate seeing the presstitutes abuse the word "sniper" by applying it to these assholes.
Rant Ends.
