No, that&#x27;s not how investigations work. The police gets some information about some crime (told by the victim, a witness, etc.). Investigates. Then asks the judge &quot;I have a potential crime here, to be sure about it I need to wiretape&quot;. The judges gives it or not.<p>After someone is convicted, there&#x27;s no use on wiretaping him about something that was already solved.<p>How simple is it to make someone an alleged criminal, well, that&#x27;s country specific. Can also be thought on how easy is to have a government receiving data directly from Facebook, or using gag orders, or bombing another country without proofs of any wrongdoing.
