3 Shootings Targeting US Military Being Investigated

On October 18 and 19, the Pentagon, the National Museum of the Marine Corps, and a Marine Corps recruiting station were targeted and hit by high-velocity rifle bullets. There's no suspects and no motive, and there were no threats, so the FBI is more confused than offended, but they are taking full measures to get to the bottom of the issue. Luckily nobody was injured in any of the shootings. They seem to be random:

On the morning of the Pentagon shooting security officers heard five to seven shots about 4:55 near the south parking lot. Bullet fragments were later found lodged in two windows of unoccupied offices on the third and fourth floor.
The civilian Pentagon Force Protection Agency's director, Steven Calvery, said last week that the Pentagon shooting appeared to be "a random event" involving a high-velocity rifle.
On Tuesday, protection agency spokesman Chris Layman said that initial description was preliminary, though officials still don't believe there is a specific threat against the Pentagon.

This is strange because there's no sense behind it. The person doesn't have any intention to hurt anyone, they seem to just be popping rounds into government buildings. I think it might be someone trying to be cool and shooting their new rifle at things they shouldn't, but I really hope they get caught, because really, what's the point? I hope that officers will be more vigilant, and maybe catch the perpetrator the next time he strikes.
