That is exactly the thing that drives charge inflation. You don't just get indicted for committing a crime, you also get charged with walking the streets while intending to commit the crime, wearing the pants with intent to commit crime, not telling the policemen you're going to commit crime, using your laptop in committing the crime, using public airwaves while committing crime, concealing your identity with criminal intent, etc. etc. That's where 30-year charges come from. I think it does indicate serious problem - why changing MAC address should be a felony in any context? If somebody did something evil and changed MAC address - convict him for something evil, not for changing MAC address. Only reason I see why such charges exist is to coerce plea bargains.
