I would find it hilarious is the assassin remained at large because people refused to snitch.
Also remember, things are newsworthy because they're novel. US sees like 2 gun deaths per day and thousands due to insurance company malpractice, but this one death dominates newscycles.
curious the man didn't use a better disguise. Just shading eyebrows, changing skin tone, a cheap prosthetic nose, maybe some gauze inside the mouth to change face shape. Sometimes the old spy tricks are the best.
