Ahh The TCP demon has reared up again. It's a harmless cumulative neurotoxin that scares the hell out of the majors and some minors too. Those goddamn sticky HBOV's causing all that fuss.
There are many schools of thought on this one because it's a big can of liability worms. I do like the MSDS on it though it tells it straight, then you read the conflicting Senate report and the House of Lords study and realise there's big money being spent and get scared and hide.
