It seemed so dreamy and historic at the time.

You just had to put one of those on your car, and it didn’t quite work out for you, now did it? (h/t reader Linda):

A paroled killer’s “Obama” bumper sticker was the break that helped cops nab the man accused of the cold-blooded murder of a Tedeschi’s convenience store clerk, jurors in Edward Corliss’ murder trial learned yesterday.

“It struck me as odd,” state parole officer Kevin Devlin testified yesterday in Suffolk Superior Court about the campaign sticker plastered on the back of parolee Corliss’ white Plymouth Acclaim.

“He’s a guy from Somerville [Massachusetts], so I was surprised he was supporting Obama,” Devlin said.

See, if you had been like this guy, you would have walked, because that would not have struck the cop as odd in Somerville:
