From Gawker:

Kirill Bartashevitch, 52, of St. Paul was arrested and charged with two counts of felony terroristic threats for allegedly threatening his daughter and wife with an assault rifle.

Police say Bartashevitch recently purchased the weapons because he was concerned that President Obama was planning to ban them.

The incident report states that on Sunday January 13th, Bartashevitch and his daughter got into an argument after the 15-year-old received two B’s instead of two A’s. The victim told a social worker that she swore at Bartashevitch and told him she “hated” him, causing him to snap.

Bartashevitch subsequently pointed one of his newly purchased rifles at his daughter, prompting his wife to stand in the line of fire. He pushed her down and then pointed the rifle at her as well.
