One of the greatest feelings a collector can achieve, especially a collector of youth, is pulling a game used jersey or autographed card from a pack. When I was 11, my mom bought me a pack of 2005 Upper Deck, and I pulled a Vladimir Guerrero jersey card. I was entrenched with it all day, feeling the swatch, imagining "Vlad" was with me, teaching me how to bat.
Then I realized there was a large crease in it, and I hadn't even noticed before due to my sheer joy. I now know that it was probably damaged by a pack searcher, who bent the pack but for some reason didn't open the pack. Now I can not even fully enjoy this great card that brings back memories.
EVERY time a disgusting thief goes into any place that has cards (hobby shops, Targets, Wal-Marts, etc.) and searches the packs by weighing, feeling, or opening, they are STEALING from collectors and especially youth collectors who have zero chance of experiencing the feeling I did.
So to all of those who search packs, and buy or sell hot packs, or hot pack secrets, please don't. It is just plain simple stealing, and more than that, immorally wrong to young collectors.
