In the meantime, the police love the camera-friendly generation. They have make investigations easier.
Once you arrest a suspect, go through his camera roll. If you evidence is not there, go to his status on WhatsApp, Snapchat, Facebook, or Instagram. Somewhere, somehow, he will implicate himself.
Sometimes, just like and share a picture and move on. Other times, drop a compliment, the person might really need it.
Just don’t let your compliment always be the precursor to them asking or being asked, “savings or current”.
