Replying to People poisoning animals

I just read a warning in a Finnish magazine, that over 20 poisoned dog food have been left over the dog parks and parks in Helsinki. Who the fuck does that?! In one park, there was a whole fucking chicken, with rat poison covering, and judging by the looks of different finds, 3 dogs have already died, and the poisons and foods point to many people doing this, not just one! What the hell is wrong with the world?! Imagine that you buy a pet dog for 800 euros, then you love it and take care of it, it's a part of your damn family, then all of a sudden it's fucking poisoned!

I've heard that people do this to bums and hobos too, giving them 10 dollars and food what's poisoned, then filming it all.
