No. There are no reports of that. There are reports of door-to-door canvassing.
Not that I condone how Boston handled the situation, but it was different because the suspects were terrorists who detonated a bomb at a public event. This is not that.
I recall the huge shoot-out where one of the brothers was run over by the other.
A fusillade by the cops, and almost no hits.
Looking for two white guys and a black guy is a little scant on details. It’s the public who usually draw the noose tight on such situations. A little more info may help besides two white guys and a black guy?
