The mail is very important. Why are there no video cameras and or GPS on these mail vehicles? The technology is there and the cost of doing this are very low. Same with mail rooms. they should all be under video surveillance.
In fact, last time I was in a post office, there were no less than 8 cameras pointed not at the employees, but right at customers at the front counter.
Now I get a daily mail with a picture of the mail that is coming that day. So if the Postman steals it, I will know.
