We imagine that being arrested on a hot, sunny day, and being bundled into the back of a police car really does suck quite badly. It's therefore hard to think of a more appropriate t-shirt for this person to be wearing on the day it actually happened to them. We have no idea what they did to merit being handcuffed and led away, but it proves that there really is a t-shirt for every occasion.
What's odd about the picture, though, is that the shirt wouldn't make any sense if the person wearing it wasn't having an experience that sucked. It would look wrong if, for example, they were wearing it with a big smile on their face at a Disney park. Sending out a negative message may draw negativity towards you - so perhaps they'd be better off wearing something that says 'everything is great' instead?
