He was committing a crime, multiple crimes in fact. I mean set aside the earlier littering that Chan had to clean up, and the trespassing that appears to have been a regular occurance and look only at the 10 minutes or so before he got shot. He trespasses on the property, enters the business to threaten arson and murder, then leaves. Then when Mr. Chan goes outside the man returns and attacks him having just told him he was going to kill him and burn the business down. I am sorry that Oregon doesn't just commit people like this who are incapable of taking care of themselves and living within societal norms like not threatening to kill strangers, but this isn't on Mr. Chan.

Good. It's a shame that it even had to go to the GJ.

econoline: Yes, he was committing many crimes. None of which carry the penalty of death though. The fact is, the business owner was not in any immediate danger. The man had left, he chose get a gun and follow him instead of locking the door and calling the police. This death was not warranted and completely avoidable.

If after I get done littering I break into your house threaten to kill you and burn your home to the ground and then I leave and then I come back later then I doubt you would be charged in the case. If all the guy did was litter then Chan would have been in the wrong, but that was by far the least of this guys crimes. The real question is if Chan had called the cops would the man have been prosecuted for his threats and unfortunately the answer is likely no. It is a revolving door with these violent homeless people in portland.
