Youngsters

Why us garda doing nothing about youngsters? You see I’m here on exchange program so I help in a non profit and few days ago I was walking down the street near Connolly and a group of 10 to 15 people in black tracksuits was looking at me and walking the same way talking nonsense to me about my Jordan’s and my watches, I just kept going straight but I don’t know what to do if they don’t let me walk ?
