SO...you want to PROSECUTE someone who has the LEGAL RESPONSIBILITY to operate a bus safely, and very likely COULD NOT stop. (There are strict standards where drivers can and cannot stop a bus, I have a CDL with passenger endorsement and have driven buses.) If he. or she can stop, you want to prosecute the driver when interfering could get said driver KILLED. My nephew's bus driver is a retired woman, about 70 years old, maybe 5'1' and 100lbs. Describe in detail how she should deal with the pack of feral thugs without using a shotgun.
Interfering can also easily get a child beaten to a pulp, possibly raped.
