Perhaps "the murder" is an swk project. I doubt it but you never know.

That'd be dope. The hidden face could be a mask. 

Probably boondox new album.   

I really hope not.

best guesses include:  
They made some shirts to promote the project, and wanna unload em    
They see that HOK merch sells and they decided to try something with SWK   
They wanna do something with SWK soon and are seeing if anybody remembers it  
Twiztid likes to make money and thought old school juggalos would get excited and buy something they vaguely remember  

or all of the above.

Unless I'm missing something wasn't S.W.K a project they talked about that went nowhere? So what's with all the shirts?
