I spend a lot of time by myself since I retired..
I do talk to myself a lot since retirement.
Frankly, I fail to see what is wrong with that.
Now I will admit that if the comments are totally off the wall or if the person is in a public place ranting something incoherent....
But this fellow was driving his car. Most of us consider our car to be a private place. Even the law considers your car a private place, otherwise there would be no need for a warrant to search it.
Stub your toe, drop your keys, suddenly remember that you forgot your wife’s birthday...cuss yourself for being stupid..
So what?
All part of being a human.
The cop is an ass.
A warrant is not needed to search a vehicle...and its not private. One can be intoxicated in public in a vehicle...
