that an off-duty homeland security agent was looking at one of the unfinished houses (that had been damaged by vandals). The agent is said to claim that one of the windows was shattered. The agent then looked out, saw a man with a rifle, and called dispatch.

Something doesn't pass the smell test.

that an off-duty homeland security agent was looking at one of the unfinished houses (that had been damaged by vandals).

Was he OFF DUTY and touring the home?

Why was he touring an UNFINISHED home?
Especially one damaged by vandals?

Was he looking at one of the unfinished houses (that had been damaged by vandals), because it was damaged by vandals?
If he was, then he really wasn't off duty.

Why would DHS be looking at a vandalized house?
