"This shooter is no dope (wacko, maybe)and isn't planning on getting caught soon. If he doesn't like the set up he's in, he doesn't shoot. There may be many people who were under the muzzle of his rifle and never knew it. I also feel he set up the cops with this phone booth thing and laughed his butt off when they popped the poor Mexican. He'll hit again toward the end of the week and I'll bet it will be back in Maryland, north of his previous shots. I truly hope and pray that he has a bad bit of luck and his weapon blows up in his face. Poetic justice and to stop any further shootings."I think you are right on the money on this (except I think he will 'hit' sooner). Also, unless (like K. Curry said) he is showing his hand because of a need for more attention, he won't be caught unless of some fluke: a cop being right there, around the corner, or his car stalls, he drops dead of a heart attack, or someone snitches him off.
Looks like you were right.
