I actually think that the tubes (apart from the one he stuck up an orifice) were probably used to make bongs......back in my teenager years many years ago, I remember boys always cutting up hoses for homemade bongs....but as for the small ones you mention above, I am not sure.
One thing, I think this guy was constantly sexually charged.........I ended up finding the search warrant and reading about toilet rolls, used toilet paper, condoms galore and used condoms made me feel sick. I know a lot of people say watching *advertiser censored* etc is normal but for some I think they get obsessed. What worries me is there was a couple of laptops and phones and blueberries and sd cards and cameras. I shudder to think of what is on them when you read that they found evidence of capital murder on his phone. He must have filmed it or taken photos
