I've had people tell me I've made statements to management about issues at work when I've been off the clock and hundreds of miles away.

First you said they had the plates from the car. Inconclusive, someone else might have been driving.

In addition, it's extremely hard to tell who is driving with 90+% of cars having factory tinted windows unless lighting conditions are perfect.

I know, let's just have us a good old fashioned witch trial......If she drowns, she's innocent. If she floats, she's guilty and we'll just pull her under and make sure she drowns.
