Criminals know that there is no reasonable escape once the doors close on a train, subway, or bus (unless the driver stops, which is rare considering he has schedules to keep and regular passengers who know him by name and rely upon him) And that is why public transportation is a HUNTING GROUND for criminals seeking an easy score, a victim, or simply to ruin the day of as many other human beings as possible.
The only acceptable public transportation is air travel. You cannot go on if you have warrants as far as I know, it’s expensive, plus you cannot move around very much at all. If you do, the stewards will yell at you. Oh and air Marshalls are armed.
Until subways and buses have such safety rails, expect more women to have their throat cut or be lit on fire while still alive when using public transportation. And the politicians who advocate for these are either looking to embezzle from their construction a la California’s light rail, or are psychos that want others to suffer. Or both.
