NEW RULES FOR PRETEXT STOPS

HERE IS THE DIPSHITS STATEMENT:

A pretextual traffic stop involves a police officer stopping a driver for a traffic violation, minor or otherwise, to allow the officer to then investigate a separate and unrelated, suspected criminal offense. … By law, police officers must observe a legitimate traffic violation in order to stop an automobile.

DAWG SAYS: SO AFTER A LEGITIMATE TRAFFIC STOP OFFICERS CANNOT INVESTIGATE ANY OTHER CRIME THAT MAY BE OBSERVED DURING THAT STOP? SOMEBODY CLEAR THAT UP FOR ME.
