We're closed!

I may not be a detective, but I think I could even guess that if I walk up to a bank and:

a.) it is sealed off with yellow tape bearing the words “CRIME SCENE DO NOT CROSS”,

b.) There are lots of police cars and police officers standing in front of the bank behind the yellow tape,

and

c.) members of the media are standing in front of the yellow tape taking pictures of the crime scene,

you might deduce that the bank is actually closed, most likely due to a robbery attempt that just occurred. You cannot enter the bank, stop asking!
