If they seen someone that fits the description of the person they are chasing (the bomber) They don't need a warrant because they saw someone that might be him go in there. They also don't know what they are working with 2 people or a group of people so they have to be on high alert.
And for people to stay inside and don't open the doors is for the protection of the people that had nothing to do with it. (no mistakes, no cross fire mistakes, no hostage situation stuff like that.)
Im a big supporter of 2A and 4A. I really think this is for the protection of the innocent.
