Pocket carrying properly is no more dangerous than carrying any other way. I can post articles of every type of carry having an ND. Does that mean no way is safe to carry? Posting a link of someone shooting themself is no more proof than saying it's true because you said it's true. NDs are caused by negligent handling, not carrying responsibly no matter how you carry it.
Fool me once, shame on you. Fool me twice, shame on me.
