Well, all we can do is suspect because your libtard media outlets cut out the beginning. Why do they always do that? Here's a fact: if you're yanking Mexicans out of their vehicles because they look Mexican, in California, you're gonna be pretty fucking busy.
The beauty of acting like a grown up with cops is, when you treat them with respect, 99% of the time you get it in return. If you want to tell them how sovereign you are, or how well you know your rights, or that they profiled you, or any number of other stupid ass comments, you'll lose.
Cops do have the right to question people with probable cause. If you act like a douche, you get treated like one.
