Only if it falls under the "plain view" doctrine, which is not unlimited:

> In Arizona v. Hicks, police officers were in an apartment investigating a shooting and suspected that a record player in the apartment was stolen. The officers could not see the serial number, which was on the bottom of the record player, so they lifted the player and confirmed that its serial number matched that of one that had been reported stolen. However, the Supreme Court ruled that lifting the record player constituted an additional search (although a relatively nonintrusive one) because the serial number was not in plain view.
