A very small city of 25,000 within a very small area with the gunman still at large? The surrounding public would be notified for their own safety. ...It's been done in my city (which is many times larger than VA tech).
Besides, it is completely inaccurate to compare a university to a city: the two are very different.
How does that translate?
BTK (wiki) - was the most recent serial killer localized in the midwest (Wichita, Kansas) and was not caught until recent - should a lock down of the town/city* ensued after the first, second, third, etc. incident according to yours and the logic of others?
When does a killer become a serial killer is it after 2 hours, 2 years,or 20 years?
It is sad to put it in such terms to say that all killers are not serial killers /mass murders. Logic would state that the original incident was a crime of passion or the such but would no longer pose future loss.
