Well, that’s how it tends to be in most places.
You don’t get caught for downloading; you get caught for uploading.

This, accompanied with CSAM and network monitoring could be used to easily get any person using the internet, in jail, just for opening the wrong link. So, the laws require much more information regarding intent and such.
