Lessons learned from Newtown shooting? #tellusatoday

We asked our followers on Twitter: A year after Newtown, what do you think we've learned? What should be done to prevent mass shootings? Comments are edited for clarity and grammar:

We need more mental illness preventive measures. The focus shouldn't be solely on gun control.

The Newtown tragedy reminded me that life is fragile and can turn on a dime. Make the most of every day and do not be petty.

Guns aren't going away! Arm the schools properly.

We learned that we don't like it when 3,000 die at once but tolerate a trickle of death.

— @navarrotells

We have learned that gun-free zones are prime targets for cowards.

— @417Francois
