In many European countries shooters are encouraged to use suppressors these days, to avoid pissing off people who live nearby (and to avoid deafness).

In the UK they are called "sound moderators" and are easy to get - you can even buy them for .22LR firearms over the counter if you say its for an air rifle.

In the US getting a suppressor requires a 200$ tax stamp, NFA registration, FBI background checks, fingerprints, and a huge wait for the ATF to process the paperwork.
