I've seen lots of such investigations fail because the evidence wasn't
strong enough to link to a particular person, but rather a computer
terminal or something like that.

Unless you also physically restrict access to such terminal to a
single person through other means (which is quite uncommon practice
except perhaps in banks), that evidence is barely circumstantial.

But you'd have to ask a lawyer in your country to be sure. I can only
speak for my own experiences in my own country which is probably not
yours nor has the same laws. Law is a complex beast.

So, you really want actual information security in addition to that
deterrent you speak of. I don't say the deterrent is bad, I only say
it's not good enough on its own.
