"An intrusion detection system that uses thermal infrared cameras to detect objects via heat sensors more than a mile away will be installed at the Meadow Avenue crossing"

Why do they need to detect people more than a mile away? There are always thousands of people within a mile radius of that crossing.

All those people are not between the rails. That's where they're re looking.
A mile in a strait line down the tracks, not a mile radius.

I'm not sure of the effectiveness of the infrared unless a) the person is hanging out for a prolonged period awaiting a train, or b) the infrared can somehow pass a notification to the oncoming train engineers to slow/stop their train.

I hope "b" is part of the plan.

Nothing can stop Darwins theory. If they can't do it by train, they will do it by car, by cop, by bridges, by guns, or knives etc....

Love starts at home, only way to stop this is for parents to talk to their children and understand what is going on in their lives. Even then, it may not be able to stop it.

Problem I see with modern family is that both parents are busy working and the children are left to the schools, baby sitters or others to teach them.

Cameras and such are largely beside the point. Like Reader says, love starts at home. And love does not mean protecting kids from every hurt, every below average grade, every puppy love rejection. Too much of that, and teens have thin skins, go bananas at ordinary HS bumps and scrapes. Parents need to let kids hurt, grow up solid.

Although it's true that love begins at home, the kind of depression that results in suicide attempts is often a form of mental illness that is biochemical in origin, and may have relatively little to do with the quality of parenting. Erecting fences to make a particularly tempting form of suicide less feasible may help to keep depressed teenagers alive long enough to obtain the help they need.

"Problem I see with modern family is that both parents are busy working and the children are left to the schools, baby sitters or others to teach them.?

Knowing several of the Palo Alto kids directly over the past few years, all that I knew had stay at home moms. Just sayin'.

"Erecting fences to make a particularly tempting form of suicide less feasible may help to keep depressed teenagers alive long enough to obtain the help they need." Long enough to find a different way.

"a form of mental illness that is biochemical in origin, and may have relatively little to do with the quality of parenting" Oh, and how do you know? What chemical produces it? It's a dead end life effect that produces it and the first one to notice is the parents, and if the parents stay in touch with their children's emotional feelings they can get the help they need. A fence will fix nothing, especially if it's a form of mental illness.

"Oh, and how do you know?"

Uh, this is common medical knowledge. A better question is how do you NOT know this. Sometimes kids are better off without the mom at home, esp if the mom is completely ignorant as to the biochemical nature of mental illness.

So you wrote "It's a dead end life effect that produces it"
Rrreeeaaaly??? Do explain to us your "Dead end life" theory as the primary cause of suicide.
Let me guess...you thought that up on your own and you have no actual document written by any sort of expert in the area to back it up, right?

Well good for you anyway, stick with ONLY what you think you know. Never go with the opinions of those highly educated in the matter if it goes against what you think is the truth...you know better than they do. Of course you do, because you think you do. That's all that matters.
