So I have a different perspective on this, as someone who has lived both in Mass and the EU, as well as other places in the USA. The only time that I can see a police detail is warranted is work on a highway, be it state or federal, or interstate highway. When Verizon was installing FiOS on my street (Medford) they had the detail cop from Somerville, doing his thing (nap time). That isn't needed in my opinion. With regard to highway details, the only request I would have is to tone down the lights. It's beyond distracting when you're driving at highway speed at night, and the strobes do everything but actually blind you.
On the topic of cameras. I'm a huge proponent of them, given that it removes human interaction from dealing with the public. The camera doesn't give a shit what race or gender you are, only how fast you were driving. My wife was blitzed in Washington DC last month but my issue with that is that the fine is insanely high for the infraction, but I think that is an American thing. $300 for 16 mph over. That along with the fact that American cameras only capture the rear of the car, which is pointless to ID the driver, but I understand that not all US states require front plates.
I honestly think that if Mass put speed cameras up, and were to do it like Germany where they rotate them, sometimes leaving them in place only a few hours, that would solve a lot of the shitty driving. Put them in the back of an SUV, a station wagon, anything. The trick is to use them on the front to get the driver. I know this well, I have been blitzed a few times. Nothing like getting that red flash to make your day go to hell, and for you to slow down. For clarification, the term "blitz" is German for flash. I'll include an edited speeding ticket for an example. It was from 2018, and I was traveling 133 km/h in a 120 km/h area. Yes, I realize I am sort of doxing myself, but that is a shitty photo of me, and I don't have that car/license plate anymore and don't live at that address.
