We stood by the window in our living room, watching the SWAT team S-L-O-W-L-Y travel down our street. Men uniformed in camouflage or in black, helmeted, jacketed, carrying large weapons. They fanned out into yards, our yard, up to doors, our door, knocked. I opened the door. A smiling team member — and it was the right thing, because it certainly helped to put us more at ease — made sure we were secure and that the suspect they were seeking was not in our Watertown home.
