Let's you look at all the things you would have looked at if you knew you were supposed to look at them at the time.
Muhammad & Malvo have had numerous run-ins with INS/FBI/local law enforcement agencies. See the below article which chronicles his time in Billingham. In one instance the FBI was notified Muhammad inquired how to make a silencer.
Suspect left danger signs in Bellingham (FBI had Terror Tip on Sniper Muhammad, October, 2001!)
Muhammad was twice court marshaled, he also had brushes with the law in Antigua, and other locations.
Malvo and his mother were detained and released by the INS.
The police spotted their Caprice 10 times during the shooting spree, but were too focused on white guys in a white van.
Hindsight? No, what I see are a lot of missteps by a number of law enforcement agencies.
Old sinkspur is all in a bind cause he was so disappointed the perp was not a white redneck. I bet he cried when Moose finally had to say those dreaded words "black man". Old sink prolly went into a lot of his usual whining, weeping and gnashing of teeth. He gets tiresome after awhile. He only comments on things he "KNOWS" about. What a laff.
