What's with the increasing amount of nutters in Dundee?

I swear I can't walk through the city centre without seeing 2-3 crazy people either arguing with a wall or trying to fight an invisible man! A few weeks ago I had a verbal altercation with a woman at the bus stops in the Seagate who was trying to pull her trousers down in broad daylight in front of everyone! I told her to pull her trousers up especially as there's kids everywhere and she picked up her bottle of Lambrini like she was gonna lamp me with it!

Everyone's just awkwardly walking by pretending it's not happening where as I feel like in days gone by these people would've been bundled into a van and given the help they need? It is entertaining at times, I'll give them that, but it feels like there's more and more of these crazy people walking around these days.
