The New England Crackdown the OP mentioned was introduced with a press conference including cars bikes and a chopper in the background. They certainly put everyone on notice that it's coming, so the notion isn't a surprise or a trap.

Speed enforcement is such a frustrating topic when you really get into it. With higher speeds come a number of unsafe developments, but everything still relates back to the vehicle and the driver. You can't tell me that either one of my cars at 85mph has a longer stopping distance than a 15 year old dually F350 at 65mph. You can't tell me that my heads-up driving at 85mph is more of a hazard than the lane-wandering of a cell-phone-using livery driver at 65mph.

Ultimately I know it would be impossible to enforce for all of the relevant factors that make driving hazardous, but it does seem easier to catch speeders than cell-phone users. I'm not sure that's the best bang-for-the buck when it comes to safety.
