I keep finding loose caps and broken seals on my milk and cleaning products. Seems that kids are going around tampering with stuff in the store. Or it could be that these things are being tampered with at the factory.
This morning I found a Carnation Hazelnut coffee creamer with the pull ring pushed in. I've had to tighten caps on bottles of soap several times. It seems that there's been a media encouraged lawless mentality that is spreading everywhere.
You should always check to see that the products you buy are sealed and haven't been opened. On most products, that is easy to verify. Anything that looks like someone handled it and broke the seal, tore the bag, or otherwise gets put back. You should do that as a matter of course. As far as your assertion that kids are responsible for tampering, you'll have to provide some evidence. And I'm not even going to address your media conspiracy theory. No reputable media source is encouraging anything of the sort.
