Protect them from what exactly? Being yelled at? Neely was an American, too, and he wasn't abducting, robbing, or fighting anyone.
How much courage does it take a tall trained Marine to jump a small, unarmed, sick man from behind, particularly when others jump in to help? Neely had not touched a single person. Witnesses say he was shouting that he was homeless and asking for money.
Someone could have called the police and said there was a disturbance. Someone could have given him $20 and there's a good possibility he would have gone away. Wouldn't that have been better than killing him?
Della, I think you may have exposed exactly how mentally ill, or those pretending to be mentally ill, make their living.
Leaving aside a citizen's right to pay for their subway ride and be left alone to travel maybe they should expect to support the mentally ill in this way.
1. Pay the transit company to ride the subway.
2. Mentally ill person gets on at the next stop and demands $20 to leave you alone. You give him the $20 and he goes into the next car to demand $20 more. You ride peacefully until the next stop.
3. Another mentally ill person gets on and demands $25 to leave you alone. You give him the $25 and he goes into the next car to demand $25 from another citizen who is just trying to get home.
What if you have 20 stops before your home stops and the mentally ill have learned that people will give them whatever they demand to keep the peace?
I think there are some other problems with your solution, Della.
Have you ever been threatened in public, at home, or anywhere? Personally, I think it would be very scary to be yelled at and have money demanded of me in a subway. I think most elderly people or children would feel that fear but perhaps you are different and you would be happy to help that poor man along in life with some of your retirement income. I think I'm pretty safe in saying that most older people couldn't afford to do that.
I would prefer to have the mentally ill removed from the streets and subways so that the sane can safely ride the subway and in lieu of that I say thank you to all able bodied men who are willing to risk their own futures to protect the weak.
