These shootings remind me of the Son of Sam killings described in the book, The Ultimate Evil. Several people were involved in the shootings. A few were deliberate hits and the other shootings were to throw the cops off. At least one was videotaped. This has eerie similarities.

I think that this is just as likely to be 'Son of Sam' style killer or killers as Islamic jihadists bent on terrorizing people. At this point there is no evidence so it's too early to say.
