What about murder? If you aren’t actually caught DOING the crime, you should be fine thereafter. Rape too. Any crime that can be completed swiftly is not prosecutable then. The jails will be full of tax evaders and speeders while the killers and rapists go free.
At what point are you ACTUALLY doing the “evading” of taxes?
Do they have to catch you right at the moment you sign the forms?
Don't be silly.
When you're put on trial for murder or rape, you're put on trial for the specific act(s) of murder or rape that you are charged with committing.
You're not put on trial for the fact that you happened to remain alive and in the area after having committed the crimes with which you're charged.
