If one would take the time to read the comments at the end of the video that is on you tube, you would see comments that this was not a routine traffic stop about tinted windows. Plenty of discussion about homeland security being involved, about the shooter being a known member of the drug cartel, about Officer Jarrott working with HS, and being set up by them. Speculation abounds that the shooter was under HS observation and Officer Jarrott was to apprehend him without the shooter alerting other cartel members (which is why he asked the shooter to accompany him back to his cruiser).

Do not know if it is true or not.

As is often the case, there is more to the story than we know and are being told.
