Have any of the attacks taken place during 9 to 5? I have the feeling they have not. This guy probably lives in the area and has a job, and his coworkers have no idea they are sitting next to the perp.

Very good point. Somewhat easier to conceal. I thought of that possiblity also. With a scope and a rest they are very accurate though you would get a good bit more muzzle blast than with a rifle firing the same round.
