wow that is crazy and sad.
Here is the thing though, everyone and their grandmother can scream all they want about safety, in which I agree, but the fact of the matter is people have been lifting weights off benches for more than a century and considering the millions of people who lift weights this has happened like very minimally and is a freak accident.
Knee jerk reactions will not prevent the one person out there who does not know their limits and accidents will always happen. Look at all those gym fail videos where people had more than one spotter.
Not saying thatn this kid was/did something stupid, but stupidity has been a factor in gyms since the beginning and will be even more so because the percentage of people using gyms the past 2 decades has exploded and will keep growing
