A few bad apples ruin it for everyone.  Are you willing to severely punish those who violate visitation rules so that EVERYONE who wasn't passing contraband can still have in-person visits or will you cry racism and call the ACLU because accountability for actions is unfair?

Judging by history and the majority of comments posted here daily I'd say the answer is a resounding no.  In fact I expect to be flagged for using an offensive term like "accountability"
