the 7.62 FMJ rounds put them down better than i would have thought.
Clearly you feel you know what ammunition the Chinese police forces are using. What is your source for that?
Also interesting to note, in this specific incident in China, the government terminated all internet services to the area, and killed all cell phone service.
All phone service from the province was greatly restricted.
Government censors worked overtime removing all comments of the riots from Chinese websites, blocking access to sites in foreign locations that had such content.
This is a normal process in China to keep various portion of the population who are unhappy with the government from knowing when one faction is acting. Preventing them from, uniting in rebellion, protesting or rebelling at the same time stretching government resources, or gaining support through any uncensored coverage.
On the specific topic of someone charging. Many threats to a civilian are not going to announce themselves from 21+ feet away, hold the weapon above thier heads, and run towards you.
They are often more subtle, and recognizing the threat is much more difficult.
While everyone is speaking of quickly reacting, the thing that makes it difficult in real life is quickly reacting the wrong way has serious consequences. People run and do unexpected things.
A person that noticed you forgot something may dart after you to return it.
A beggar may suddenly run towards someone to ask for money.
Someone may dart out to ask about a vehicle, or other item you possess that interests them.
A man may dart out after a woman who is a total stranger to ask for a phone number in strange places like a night time parking lot.
All total strangers. Yet every one could have just as easily been a threat, and a failure to act until they were in arms reach giving them an advantage.
Additionally the real threats often don't reveal themselves as threats until within almost arm's length away.
I have also seen groups of young men and gang members come out acting friendly, sizing up the victim before they attack.
Even if you know they are trouble, that is an assumption, not a legal justification for taking any hostile action.
How would you justify shooting the group of say teenagers or young men acting macho before an actual threat or hostile act? There is nothing illegal about anyone, even a group of thugs walking up to or even surrounding a person. You can't make the defense in court that you "thought" they were up to no good.
They may proceed to attack, beat, or rob the individual, but until that point absent a verbal threat or visible weapon the threat is an assumption.
Not acting lets them position themselves into a dominating position, where even if you went for a gun they could tackle, grab the arm, or attack as a group including with weapons not yet revealed.
Even pulling out a firearm is assault with a deadly weapon/aggravated assault (depending on state) before lethal force is justified. Both serious violent felonies.
If anyone is a threat before that distance , you might as well have your weapon at the ready and unholstered already.
Unholstering your weapon and having it ready before a threat which justifies lethal force is felony assault.
You may think the group that just stood up and is walking towards you is a threat, but will a court of law agree?
Even if you did something that may have upset them, can you convince a court of law they were not just coming over to talk to you?
The truth is they have every legal right to walk as close as they want to you, before revealing themselves as a threat. At which point they have a decided advantage.
Pulling your firearm out against something that may be a threat, even if it is a man coming towards you in the middle of the night in a dimly lit area with nobody else around, and you think they have no legitimate business acting as they are, is a felony assault.
