Exactly!
"For us, revealing that evidence through the media is just not what we think is appropriate. We want to make sure that this individual is held accountable for these egregious acts. For us, we’re going to make sure that we limit the evidence as much as possible in order to get that done,"
The goal here is to make sure this guy is held completely responsible, you don't want to release evidence that might muddy the water. For example, suppose video evidence shows that the official narrative is false, then you get the whole media talking about that rather than about convicting this homeless man who has been influenced by watching Jesse Waters on cable TV to attack Paul Pelosi and to imitate the January 6th insurrection. Look how sinister it is to have a guy with no discernible ties to Trump or MAGA, even his girlfriend didn't know.
No right now this story is hanging together by a thread and the only way it doesn't break is if you limit the evidence as much as possible. The official narrative is that this was politically motivated attack and nothing is going to be released that will contradict that until after this election. Kudos to the DA for not making this political.
