I'm afraid I see it as absolute par for the course that no-one in the L.A. Police Dept gave a thought that a train might come down the track, with potential to kill or seriously injure many passengers plus train staff in addition to train occupants. I will admit to becoming rather addicted to You Tube videos of American police chases, a large number featuring Californians, and there's what I regard as a collective madness on show,and not just by the criminals being 'chased'. For anyone who doesn't know, police policy there is that any car failing to stop as requested, no matter how it's being driven and by whom, is to be 'tailed' for as long as it takes, which in the case of L.A. can become hours. This 'tailing' can involve dozens of police vehicles, marked and unmarked, and police and TV/radio helicopters, often broadcasting live. There is rarely any attempt to bring the vehicle to a stop, even if it's only being driven at 30 mph, which it surprisingly often is. More commonly, other cars get damaged and lives get disrupted, even ended. The mantra appears to be that no police officer must get injured, let alone killed, during the chase but the public are co-lateral damage, Even when a car being driven by a 68 year old grandmother lone occupant comes to a halt, dozens of armed police must take position yards away and try to coax her from the car in case she comes out armed and dangerous and puts paid to them all! This can take a further hour, in which time all traffic for miles around comes to a grinding halt. It's madness and overkill, but everyone involved on the 'authority' side is wedded to it, hence the situation with this plane on a railway where nobody gets delegated to find out whether a train might just suddenly appear on that track: if nothing else, why did nobody start running up and down those tracks ready to wave down a train and, potentially, avert or make far less likely a deadly outcome? Group thinking leads to group ignorance.
