The attitude of most Americans have towards government, it's agents, hired guns, cops, call them what you will, is no longer sunshine and lollypops. You haven't noticed?
There are reasons for this sea change of attitude.
Just like the cops arrogant ruling class political bosses. The cops need to start treating Americans on the streets like free humans, not enemy in some 3rd world combat zone.
The cop could have easily handled this with just a bit of common sense. Instead of "obey me or else", us VS them attitude. This was a traffic infraction, with a single female involved. Not a felony stop of suspected armed bank robbers or terrorist. And this was pretty obvious to the cop in this incident.
This is not complex. Law enforcement need to come to grips with the fact that Americans are a free people who expect to be treated like free people. Not prisoners of war who will be caged or killed if they fail to immediately comply. That don't work for Americans. They best learn this or their stock will continue to plummet.
Most cops, especially those in TX, are Oath Keepers and will be the ones on the front lines to protect you against the tyranny of the feds. Don’t paint all cops with such a broad brush.
Yes, the cop was rude, but that does not excuse her refusing a lawful, valid order and it does not excuse her assaulting the cop. Before automatically hating all cops, try riding out with them and see what they see. Your perspective will most likely change.
