Police arrested CU-Boulder student Max Karson on suspicion of interfering with staff, faculty or students of an educational institution.
CU police Commander Brad Wiesley says Karson made comments about understanding how someone could kill 32 people - during a class Tuesday.
Students reported the comments at about 1 p.m. Wiesley says people in the class interpreted Karson's statements as threats.
However, Karson's father, Michael, says he thinks his son's remarks have been misinterpreted.
Max Karson is expected to appear in a Boulder courtroom this afternoon.
Authorities say 23-year-old Virginia Tech senior Cho Seung-Hui shot and killed 32 people on that school's campus Monday before turning the gun on himself.
