In the real world, accidents happen, and a well documented phenomenon like spontaneous glass breakage is actually specifically a potential side effect of toughening the glass. The alternative is to have regular, non tempered glass that breaks into large shards that will cut someone's entire face and possibly leave them blind; is that what you'd like? Judging by the photo posted, it looks like the glass did its job, and the kid got a few cuts on his arm and leg. Unfortunate, but much more preferable to the potential damage that non tempered glass would've done. I don't think the fault lies in the glass panel, which did its job, nor the manufacturer as the install was clearly successful enough to last the past few years. Maybe we should push for legislation to mandate laminated glass be used at public entry points? I don't know, but you're definitely attributing blame to the wrong party here.
