While more than a million people were told not to leave their homes in the Boston area Friday, much of the nation has been captivated with the search for a suspected bomber.
While the tactical teams have pulled back for now, much of the day was spent going door-to-door looking for the remaining suspect. Investigators said they covered 20 streets, every house, and while they haven't found Dzhokhar Tsarnaev, state police believe he's still in Massachusetts.
Dean Olson spent 30 years as an investigator with the Douglas County Sheriff's Department. "I worry about these officers out there.”
He's retired now, but is still head deep into law enforcement. Olson wrote a book, “Tactical Counterterrorism,” a playbook of sorts for ground level officers and deputies to follow when it comes to spotting potential terrorists during traffic stops and such.
“If they're cornered, they may decide to blow up themselves and take as many first responders and police officers with them,” says the retired captain.
A bulletin came out to local law enforcement a few years ago warning of just that. Olson believes there's more people involved that just the two brothers. “I think as this thing unfolds, I wouldn't be surprised that there is a cell operating and a bomb maker.”
As the manhunt continues in New England, locals know that there's much to be learned from what's taken place in the last few days. Omaha has big events attended by thousands. This is a reminder to stay vigilant for all of us.
"The Chechnyan background is fairly significant because they've had several groups aligned with al-Qaeda and when they invaded Afghanistan after 9/11 they found dead al-Qaeda fighters who had blond hair and blue eyes."
