One of the strangest things about watching heavily-armed tactical teams sweep through Watertown, Massachusetts in search of Dzhokhar Tsarnaev, the fugitive Boston marathon bomber, was seeing all this war pouring through quaint suburban streets. Helicopters landed on the roof of the mall. Men with M4s perched on backyard huts. Cheery lawn ornaments decorated the yards while police pointed guns at the windows next door. Some of the most surreal pictures were taken by residents from their upstairs windows as law enforcement patrolled their streets and camouflaged military vehicles parked next to trashcans on the sidewalk. Here are some of the most arresting photos from Watertown.

Andrew Kitzenberg tweeted this photo of the neighborhood being evacuated "by military with assault weapons."

Karen Pryor tweeted her house was searched at 7a.m. It looks like six soldiers on someone's back porch.

"There goes the neighborhood," @jw2840 tweets.

It's not just the police and FBI. It's the press, too. @yushaSays says this is what it looks like outside her door.

Earlier this morning, it looked like this:
