Witnesses Saw Man Pouring Suspicious Powder On Mailboxes (Ohio)
Witnesses saw a man pouring some kind of powder all over mailboxes on Wayne Avenue in Dayton Friday evening, police said.
The powder was white and came from a small, plastic vial, police said.
Police said they do not know what was in the vial and postal inspectors were called to investigate.
Even if the powder is harmless, the suspect could still face federal charges for tampering with a mail box, police said.

Yep, tampering with a mail box IS a federal crime.
Updates appreciated on this, too.
