Officials in Kaiserslautern and Landstuhl recently laid bare two big cultural differences for Americans.

First off, people here are trusting enough to leave their car doors unlocked. Secondly, police apparently don’t need a search warrant to open the doors and hang on to things for safekeeping.

Police departments from the two cities joined Army military police and Air Force Security Forces to check for unlocked cars along roadsides and in driveways. They found 110 of them on Thursday night alone, according to a Westpfalz police statement.

In all but two cases, police were able to contact the owners. One car owner had “valuable tools” seized from his unlocked car to prevent them from being stolen, the statement said.

The special operation was part of a police information campaign geared around getting people to — you guessed it — lock their doors and stop leaving expensive stuff showing through the windows.
