Check this out! Have you ever seen so many black SUVs and beefy dudes dressed in black before?!

Check out the video above -- there were at least six black SUVs outside of Justin and Hailey's house, waiting in the street, with a few guys walking around monitoring the situation.

Of course they had their face masks packed and Justin, his Crocs ... wait, his CROCS?! Yep ... check this out!
