"It is unimaginable that terrorists could launch a prolonged attack on an urban target in a Western country and that police would not respond quickly enough to engage them at the scene."
It's not at all unimaginable. For two years I've been imagining far more serious attacks made possible by millions of unvetted illegals being turned loose in the USA. Just suppose a tiny percentage of them coalesced in a few urban areas with a plan and weapons. They could easily overextend available police resources. Mobilizing state and federal assets would take hours. I do not believe we are taking the lessons of September 11, 2001 seriously enough. We have fanatical enemies.
