Just spent lunch driving around Belfast in Streetview, those murals are pretty mad, who paints them and why? Does it make you a bit of a target?
Most of the paramilitary ones are commissioned by the respective paramilitary group ie U.V.F. So no, it won’t make you a target since the person painting them will be protected by the terrorists themselves who act with complete impunity regarding the law. This is why they can be painted in broad daylight on the side of residential houses whether the home owner likes it or not.
Ones which aren’t explicitly controversial or sectarian might have funding/sanctioning from community groups and the like.
