You’re exactly right. Now that you mention it they are all alike. Same stupid grinning up close to the lens, same flashing of bling, money, etc. usually gang signs. I suppose they see their friends seeing them. Their gang buddies are their audience. There’s about a gazillion of these photos with little variation.
All the time I read about a robbery or some other crime and cops finding them on Facebook flashing the money. They’re freakin idiots. Look at this, just a fast search and all these examples come up.......
