I was curious myself about Platties coz the angling shops hardly stock them, if at all, they keep saying it's not allowed & whatnot. Visited the NSPCA website trying for info abt them, but nothing. Seems nobody really knows what the law is, if like you say even the peeps who should be upholding any law regarding them dont know. I've only read comments that it's unlawful to use them as live bait, they need to be killed before being hooked. Judging from the episode about chics on special assignment (or was it 3rg Degree...?), I suppose it's got to do with animal cruelty & treating animals humanely & not inflicting unnecessary cruelty & suffering on them. Rather they be killed by us than suffering first. Makes sense if you think about it.
