Correct me if I am wrong, but this seemed to be pretty intentional, and if the victims were randomly chosen, then aren't we back to terrorism?
Right.... if it were random, it wouldn't have been targeted at city officials... This was somebody's personal issue, and not likely a random one.
I think the problem is that the definition of terrorism means "Muslims" and "random" or "isolated" means "not on Al Quada's direct payroll" and we get caught up in semantics. There are plenty of criminal acts that can be committed to further plenty of political agendas that have nothing to do with the middle east. Muslims do not have a 'lock' on bad public deeds in the name of politics, but our vocabulary has not caught up to the new world.
