That sound you hear...

... the fourth amendment going down the toilet:

Supreme Court says police may search even if arrest invalid

David Lee Moore was pulled over for driving on a suspended license. The violation is a minor crime in Virginia and calls for police to issue a court summons and let the driver go.

Instead, city detectives arrested Moore and prosecutors say that drugs taken from him in a subsequent search can be used against him as evidence.

"We reaffirm against a novel challenge what we have signaled for half a century," Justice Antonin Scalia wrote.

Scalia said that when officers have probable cause to believe a person has committed a crime in their presence, the Fourth Amendment permits them to make an arrest and to search the suspect in order to safeguard evidence and ensure their own safety.

Don't spit on the sidewalk. Any cop that may see it can now give you a full body cavity search for it.
