Let's face it: Most end-user computers are compromised in one way or
the other.  This doesn't mean that the legitimate owner of the machine
isn't using it for any crimes.

It's standard practice in some countries, especially when mere
possession of data is not automatically a crime.

If you do this, anybody who is interested in child pornography just
infects his machine with some malware and escapes conviction.  This
isn't quite feasible, either.

As long as the possession itself is a crime, this is just a waste of
resources.  I tend to agree that the current situation in most
countries is difficult because of the elusive nature of purely
electronic evidence.
