A federal appellate court struck down an attempt to void Sunnyvale’s restriction on high-capacity gun magazines, saying the ordinance is a reasonable effort to prevent gun violence.

Everytown for Gun Safety, a gun control advocacy group, has kept a running tally of campus shootings since the Sandy Hook massacre that left 20 little children and six adults dead.

Sunnyvale's gun control measure, which includes a ban on gun clips holding more than 10 rounds, doesn't violate the Second Amendment, a federal judge ruled Wednesday.

Saturday marks a year to the day since a gunman killed 26 students and teachers at Sandy Hook Elementary School in Newtown, Conn. To remember the lives lost, a group of community leaders and activists will hold a vigil this weekend in Sunnyvale, a city that grappled with a massacre of its own in 1988.
