That's (almost) how it works in Italy. Mostly it works like this, if the maximum sentence for a certain crime is X years, if you are not sentenced after X years (if X is less than 6 years, then use 6 years) you are no longer triable.

Unless the maximum sentence for the crime is a life sentence, in which case, you are always triable.

And of course it is a bit more complicated, as there are certain rules on "when the clock starts ticking", and "when the clock stops ticking" and "when the clock is paused for a bit".

Which in my opinion is fair, although there were some people that abused the system to try to avoid a sentence, which is bad, but I think that in general a few bad people exploiting a good rule doesn't mean the rule must be removed. If anything we should change the rule a bit to prevent such exploits.

Nice try but we'll never stop hunting you for what you did in Bosnia

A lot of Nazis got away like this

Sorry if there's been a misunderstanding on my part.
I thought the "Thankfully" was detached from sentence 1 and 2. With sentence 3 referring back to OP.

My reply was thus also referring to OP, along with the Putin pun as it fit there.
