In Colorado, the site of Friday's shooting that killed 12 and injured dozens of others, gun sales jumped in the three days that followed. Numbers also show a bump in places like Florida, Oregon, California and Seattle's home county.
Shop owners say customers are concerned that lawmakers might try to push through an anti-gun agenda in response to the shooting, which killed 12 people and wounded dozens of others.
Others are interested in making sure they are able to protect themselves if they were ever in a similar situation.
