However, based on the article, there's an apparent lack of law enforcement interest due to jurisdictional challenges. Perhaps it's also harder to get govt funding for something as 'routine' as attempted murder vs headline fodder like pedos.
I imagine there might be an opportunity for a reality TV producer to create a "To Catch a Murderer" show along the lines of "To Catch a Predator." Once they have a real 'client', they could let the client know a date and time for which they'll need an alibi and then suggest a nearby location that has video surveillance by which the would-be client can establish their presence.
That creates an oppty for the host of the show to approach the client at the alibi location, ostensibly to return the client's money because there are 'problems' with the hit. The ensuing conversation would likely lead to some high ratings as well as broadcast-quality, multi-angle indictment evidence.
