The US has 3 different branches. The president is the head of one of the branches called the executive branch, which is the branch that enforces the law. Every president, at least in modern times, selectively chooses when they enforce laws and how severely they enforce the law. The DOJ, department of justice, is part of the executive branch and is involved with such matters.

The selective enforcement of laws is a hot button issue and both sides accuse the other of doing it. (Both sides do it all the time).

As far as I know, every country has similar issues. I constantly see articles where people are allegedly being prosecuted because they are on the opposite side of the government leadership while also seeing articles claiming they let their own side off.
