No, its you who doesn't get it. The "dirt" came from the emails and THE EMAILS WERE STOLEN.
Breaking into a computer and stealing private documents & correspondence is a criminal offence (just like breaking into a hotel and stealing documents from the headquarters of an opposition party) is a criminal offence - sound familiar?
► If Trump only found out the emails were stolen after they were stolen, and still received them, or information from them, that makes him an accessory after the fact to the theft, and he has received stolen property. Both are criminal offences.
► If Trump knew the emails were going to be stolen and received them, or information from them, that makes him an accessory before the fact to theft, and he has received stolen property. Both are criminal offences.
► If he asked for the emails to be stolen (he did so publicly - that is on record) and received them, or information from them, that makes him an accessory before the fact to theft, and he has received stolen property. Both are criminal offences.
► If he colluded with the Russians to steal those emails, even if he never received them or any information from them, then he has participated in a criminal conspiracy to steal those documents.
