Lock down is something we are all to familiar with when it comes to bomb threats at our schools but to imagine having your entire city and surrounding cities on lock down is almost unheard of. Due to one suspect dead. One at large. Armed and dangerous it is absolutely necessary that the entire city of Boston and some surrounding cities continue in lock down. This means some people are being escorted out of their homes even if they are unaware of the lock down. All business's, public transit, schools, etc. are closed. People are being urged to stay at home and not answer the door for anyone but police officers. Residents of Boston are living in fear right now. My heart goes out to them. I can only imagine what it feels like to know that a killer could be anywhere in the city my family and I live in.
