Well yeah, but the police will ignore the laws, do a parallell reconstruction, and do whatever they want.
We must take away the tools that make their illegal works possible. One of them are imsi catchers, the other is location access to apps on phones, especially when the app is closed, then better authentication schemes must be implemented (some of it is done with 5g, but eg 2g is completely broken), etc.
IMSI catchers are not passive listeners, but actively transmit and act as if they are a legit tower and let phones connect to them, identifying them only because phones send identifiers to them. Passively listening to signals doesn't do much on newer networks and even with older (eg. 2g) only works if you capture the first connect to the network (when IMSI is transmitter, after that a temporary TMSI is used).
