Has been rather more prominent in the news over here in China, as you'd expect. Looks like the guy did it to as a suicide mission due to
heavy gambling debts. Stuffed some firecrackers in a beer bottle and blew it up at the check in counter, before attempting suicide by cutting his throat. Obviously not great, but better that he only had a few firecrackers rather than a fully loaded AR-15 to do the job with, as we've sadly recently observed.
One of the more practical issues from this incident is that authorities will now require security screening
before you enter the terminal at PVG. Don't know if it replaces the regular screening (doubt it, myself). Not really sure how effective it would be. Just moves the attractive target of a large group of people a few meters over, I reckon.
