Per multiple news source (e.g., SMY), he was approached by team staff upon arrival and asked to leave immediately. The fact that he took an hour to do that doesn't make a difference.
It seems that to me, that at this point in time, it is pretty much impossible to conceive of him as an innocent witness.
Pretty much impossible? Based on what?
Let's put it this way - what if Aaron and his friends went to buy some weed or some other ****. Which, he does have a history of marijuana use so that's not a giant leap. Let's say his ex's sister's boyfriend Lloyd, who was an acquaintance of Hernandez, asked if he could borrow the rental car they had used for the drug deal and he drove off to the park to make another buy while the rest stay in Aaron's home getting high. Lloyd was then the subject of a deal/mugging/carjacking gone foul. The mugger/carjacker gets in the car and drives off in a panic, realizes the car ties him or her to the murder stops a little ways away, gets out and runs off.
Hernandez, learning that Lloyd has been shot, now fears an investigation where the drug use in his home will be seen by police investigating the murder and in a moment of panic based on not wanting to get caught for drug charges destroys the equipment.
The next morning he calls his lawyer after his regular Monday house cleaning crew comes in and his lawyer tells him what an idiot he is because obstruction of justice in a murder trial is way worse than getting caught doing some rails off of a hooker's *******.
Now the media gets into the story and they see the juicy narrative they want to push. Now instead of a regular house cleaning crew coming in for their regularly scheduled cleaning the story is delivered in a way to imply a narrative - that Hernandez called them to clean up blood and brains. Stories about Hernandez being in trouble in other instances come up and now instead of isolated incidents of bad judgement, which all of us are guilty of to one degree or another, they're presented as a sort of overwhelming evidence of his poor character.
He didn't almost get into a fight with a teammate like happens all the time on sports teams, no he was
THREATENING Welker.
He wasn't asked to leave Gillette because of the media circus disrupting an event with Gov. Patrick he was
BARRED from entry.
If you can't see the obvious attempt by the media here to frame events to tell the juiciest story then you should probably take some classes on social engineering.
Meanwhile it could be nothing more than a kid panicking after doing something millions of Americans, including our president, do and have done, now he looks like he's trying to cover-up a murder and people like you already have him not only off the team but swinging from the gallows.
And it really bums me out because it just shows how much power the media holds over public perception.
