Reading this, I think it's a crime that this guy is not out on early release. The majority of his sentence was for marijuana, which is now widely decriminalized and in some places legalized.
I do not believe this is true. Looking at the record, marijuana is one of a few drugs. The specific incident that led to his current sentence is related to a powerful opioid. This is corroborated by Preston's own personal website.
If police can determine there is probable cause they can immediately search without a warrant. It contains strong evidence of him committing harm directly to his gf at the time. It does not contain a legal decision or conviction, but that's not a lack of evidence - the report's existence itself is by definition evidence.
That’s false. PC needs to be taken to a judge for a search warrant.
What you are probably thinking of is what is called the “exigent circumstances” warrant exception, and it was misapplied here by over-zealous police who violated his rights.
There is no evidence to support that the injuries sustained by the woman in his apartment were caused by him, according to that document.
