Repossession is never pleasant, and while it can sometimes be avoided, pulling a gun on the tow truck driver is a guaranteed way to make a bad situation far worse, as one man quickly discovered. His rash decision brought immediate regret.
Threatening someone over a repossession turns a financial setback into a criminal matter. The episode is a pointed reminder that however frustrating losing a vehicle may be, escalating to violence only compounds the trouble dramatically.
Caveat that many used car dealers do in fact abuse the repo system ie losing your 2nd to last payment.
