New York Mayor Michael Bloomberg says he trusts the police and feels "perfectly safe" despite the ricin scare.

Bloomberg said Friday on his weekly WOR Radio show that threats come with the job.

He says he faces "more danger from lightning" than from anything else.

Police Commissioner Raymond Kelly said Thursday that poisoned letters sent to Bloomberg and the group Mayors Against Illegal Guns threatened to shoot anyone who tried to take the sender's guns away.

In Washington, the Secret Service disclosed Thursday that a similar missive was sent to President Barack Obama.
