The ban on guns for taxi drivers is coming from the cab companies. The policy means drivers are forced to find other ways to protect themselves. [More]Carry anyway and don't tell them--it's none of their damn business. The worst they can do is fire you, and they'll never know unless you need to protect yourself, at which point, a crap job will be the least of your worries.
And take some classes and get a better job. The hell with those selfish pricks who would let you die.
I wonder if the pistol-whipped driver the video talks about is going to get a lawyer...? It's not like the cab companies can claim ignorance.
If you're ever in Yuma and need a cab, call and ask if they allow their drivers to carry. If they say "No," tell them you won't do business with them and rent a car. I just checked--you can get an economy model for a whole day for $26 plus gas.
