I’m not doubting you at all, but could you please provide a link to information about the .22 being the murder’s firearm of choice?

I had heard it a while back (on some media show).

So I was just googling to verify it, but haven’t found it yet.

All the data I find is pretty old, and it all seems to be using the same statistical data. Here is a sample:

We have to always keep in mind the trends on firearms.
20 years ago, a 70’s model car was most driven, today it is not for obvious reasons, th same hold true for these statistics, I doubt they are even close to being accurate, but do take note of the trend towards larger calibers over time.

It’s common knowledge. The most used method for assassination type hits is a 22 rimfire pistol fired once into the back of the head. 22 ammo is so common it is virtually impossible to trace. 22 firearms are so common people buy and sell then so often, that there is not an accurate registry to track down who owns what. Often, the 22 pistol is made from a bolt action rifle that is cut down to a pistol.
