If you discover one can that has botulism on your shelf, what do you do?
You remove all of the cans off of the shelf, even though the vast majority might be perfectly ok.
It’s not the same. Truely not all Muslims are potential terrorists. Any of the other cans might have botulism. However, my anecdote shows that Muslims are unlikely to fight against the evildoers among them.
I remember the Night Stalker terrorizing SoCal in the 1980s. He’d break in and kill and maim using all different methods. He stole a few cars, and in one he left wiped but still detected prints. So the cops were closing in on him. Once his image was on tv, he had a harder time hiding. The day he was caught, he had been hiding in a community that looked like him, a Hispanic immigrant community. They were so proud of catching him, beating him, holding him for the cops. That is what we need to see among the Muslim communities. We hear nothing. Sure, a March for peace here and there. But NO CONDEMNATIONS of their brethren, no sleuthing, not much reporting.
(Though sadly some of the parents reported their kids, but authorities didn’t follow through in time)
