Jason was furious with them. How could they be on guard yet not see the person who delivered the package? It was their job, and they were paid for it, to watch over the house and most importantly keep Bernadette and Walter alive.
Bryan shared his feelings but he didn't care about the security guards at all. The security footage only showed a shadowy figure leap across the entrance. From the look of things the person was a professional.
Bernadette followed the officers outside to check one more time on the damages. She had thrown the bomb far away yet the resulting explosion managed to break her glass windows and rattled her door. It blew up part of the house that stood next door but thankfully no one was killed.
