The problem here is that some people think gun owners should keep a low profile, never cause a fuss, and hope that no one ever knows that they are gun owners.
Sorry! We don't keep our rights by keeping quiet and hoping no one notices us.
Some people think that what ever a cop wants must be okay. They don't care if their car is searched without probable cause, they don't care if they get stopped at random on the street and get frisked, they don't care if the cops order you out of your house at gun point and then search it without probable cause or search warrant, (don't believe it happened? Boston, during the lockdown after the Boston bomber shootout. Police ordered people out of their houses at gun point, and searched them) Greensburg, Kansas, after the tornado, people were illegally ordered from undamaged houses at gun point, police later searched and confiscated guns from those undamaged houses. And of course New Orleans after hurricane Katrina.
Many, many other incidents, all of which have been defended by unthinking supporters of Law Enforcement, on the grounds, "they are just looking out for the welfare of the community", or "it's no big deal, it is in the name of public safety".
All police States justify themselves in the name of "public safety".
Look, if they had just stopped and talked to these guys, identified them, then maybe kept an eye on them... no problem! That is what I would expect.
But handcuffing them in the back of a squad car for 45 minutes, while they tried to come up with some excuse to arrest them, and attempting to erase the video, is beyond what should be accepted in civil society. The police abused their authority, and violated their civil rights.
My Father was a truck driver, who often handled wide loads, and the Highway Patrol hated trailer house drivers at the time, and would always stop them, give them an extensive "safety check", and inevitably "find" something they could write a ticket for. I remember more than once, them going over the truck and trailer several times with multiple references to their book of regulations trying to find some fault, no matter how small to write a ticket. Somehow, they always did, even if it wouldn't hold up in any court, because they knew it would cost the truck driver more to fight it in court, than pay the fine.
Like I said earlier, not all cops are thugs, but many are!
