I lost all respect for the system after the nth time I saw someone zip into a handicapped spot, put up the tag, jump out of the car and run into the mall.

Abuses certainly happen, but even in that scenario, how do you know the driver isn't picking up a disabled passenger?

I am certain that you can conjure legitimate-sounding explanations for any behavior observed at a handicapped parking spot so why did you bother to prepend this explanation with “Abuses certainly happen”?
