Wiring Horrors found while correcting an Exit Signage Issue. Some people just do not get what danger they cause the public when they play electrician

Recently I was called to troubleshoot an issue at a Flea Market Complex which was having some issues with Exit Signs not working when I ran across this mess most of which I corrected ,but more work needs to be done because people setting up booths often play electricians and every time you turn around you find another horror story at places like this  all over the Tri- State Why people think they can do there own wiring and think they do not have to follow codes in a public place is beyond comprehension but it goes on all the time . and as you can see below wires where cut off spliced with out proper connectors and junction boxes and just taped. The booth owner got mad when i cut the wiring off and told him fix it or take it out said he was going to sue me blah blah blah I said fine call police and I will call code enforcement. .he was eventually evicted by owners.
