Depends on what?
The caller would have to be pretty darn ignorant if he even dreamed he would ever collect a dime from such phone calls, and just as clever if he thinks the LEO will take any specific action on the called in "violator" based on such phone calls of non events. The best that could be hoped for is an enforcement campaign that is far more likely by writing or talking in person to the appropriate LEO or political officials.

If anyone has evidence of otherwise, inform me.
