Doing a phone consultation with a gentleman who was arrested for possession of marijuana under 2 ounces. It looks like the officer might have made a bad stop; we'll have to look at the dash cam video to know. An officer has to have a valid reason to make a traffic stop. Looking tense as you pass by is not enough. If they don't have a valid reason for the stop, it's often possible to get the evidence suppressed and the whole case thrown out. But a bad stop is not the same as a bad search. And a bad search doesn't always equal a bad arrest. There are a lot of factors that go into whether a police officer followed correct police procedure and whether their failure to do so would lead to the suppression of evidence. A top criminal defense lawyer will know where to look, what's important and what's not. Police officers learn that bad police work is often good enough. In fact, they may not even know they're doing things wrong. But if sloppy procedure is never challenged it does the job.
