pushing me back. people don't seem to be panicking any more at this point. as it looks now, the police look like they have it under control, at least where i am. there's just -- they're just really pushing people to safety. i don't really see many people in stores any more. everyone is just trying to move along the street. >> ali, looking at the calmness that we're looking at on the screen and that catie is describing, it does appear that london authorities have a playbook about this. unfortunately, they've gained much of that playbook because they had to deal with terror attempts. they were able to clear out. it's kind of remarkable looking at these pictures. particularly the ones on the left side of the screen. this is london. at rush hour on a friday night. on black friday and you are seeing entire city streets cleared out. this is a testament to their ability to do this.
