The teen accused of shooting three people at a Black Lives Matter protest and killing two of them made his first appearance in court Friday. A lawyer for Kyle Rittenhouse, 17, claimed he fired in self-defense. But Wisconsin law states that only people over the age of 18 are allowed to legally open carry guns like the assault rifle Rittenhouse had. The two victims' identities were made public. Joseph Rosenbaum and Anthony Huber lost their lives after allegedly being shot by Rittenhouse.
