Strength, solidarity emerge in wake of cowardly attack.

The evil unleashed on the Boston Marathon did not cripple that city's spirit.

It did, however, produce an impressive show of strength and unity.

When bombs exploded Monday near the finish line of the Boston Marathon, scores of people became victims. The explosions left three people dead and more than 170 others wounded, with many still in critical condition.

Sadly, the attack was another grim reminder of our vulnerability, and the price we sometimes pay in a free, open society. Expect future high-profile events to include even more security than we've become accustomed to since the bombing of the federal building in Oklahoma City and 9/11.

Because of the latest terror attack, grim images of bloodied spectators hit by explosions of ball bearings, nails and shards of metal will be etched in history as will the amazing acts of those nearby who went to the aid of the injured in the midst of a frightening scene.

Whether it was police officers, medical personnel or others who lined the street to catch a glimpse of runners finishing the famous race, so many good people reached out to help the wounded, and no doubt saved lives as a result.

Their actions turned into bold statements of the courage and solidarity that emerged. And, their determination should carry over to those charged with bringing anyone who sets out on a terror mission to justice.

Although video of a suspect was located, authorities had yet to say Wednesday who might be responsible for the cowardly act targeting an event taking place on Patriots' Day, a Massachusetts state holiday commemorating the opening battles of the Revolutionary War and a day set aside to celebrate the independent spirit of Boston and the nation.

As heartbreaking as the horrific attack in Boston was, the response was equally heartwarming at a time a troubling number of people across the globe would rather devote their lives to terror and hate.

Such evil-doers could learn so much from the courage and integrity of those who chose to help rather than hurt people Monday in Boston.
