Columbine
19-year-old Alvaro Rafael Castillo opened fire at Orange High School with a rifle and shotgun, shooting eight times and wounding two students. Officers ordered him to stop firing and he immediately complied. Castillo killed his father with a firearm before driving to school in a van. In the van police officers found ammunition, pipe bombs, and other weapons. Castillo will be charged with first-degree murder in the death of his father while charges for the school shooting are pending.
A 13-year-old student fired a cheap imitation AK-47 inside his middle school after confronting two others students and his principal. The student was wearing a mask and had pointed the gun at the principal, the assistant superintendent and two students. After firing a shot into the ceiling and breaking a water pipe, the student's gun jammed when he attempted to fire additional shots. The student was then confronted by police officers and taken into custody. Officers also found a note in the student's backpack indicating that he had placed an explosive in the school (which has 700 students). No one was injured in the incident. (even though it doesn't mention if there was a bomb or not)
Two pipe bombs went off in a hallway of Hillsdale High School, in San Mateo, California, during the beginning of first period classes.[288] Nobody was injured from the explosions.[289] Alex Youshock, a 17-year-old former student of the school, was held by staff members until police arrived and was found with eight other pipe bombs, a two-foot-long sword, and a chainsaw concealed in a guitar case. Youshock was subsequently arrested and charged as an adult with eight felonies.[290][291]
De Anza College student Al DeGuzman planned a Columbine style school shooting at the school. An employee at a Longs Drugs store developed pictures of DeGuzman posing with his guns and homemade bombs. She and a coworker called police. DeGuzman was arrested when he returned for his photos. Police found Deguzman's bedroom stacked from top to bottom with sophisticated handmade bombs and a map of De Anza College, marked with locations where bombs would be placed. [9] In October, 2002, DeGuzman was sentenced to seven years in state prison.[408] He later committed suicide by hanging himself in his jail cell.
Jeremy Getman, 18, planned a school attack at Southside High School but it was foiled after students told a teacher that he was carrying weapons. He carried 14 pipe bombs, three smaller bombs, a propane tank, a sawed-off shotgun, and a .22 caliber pistol into the school by a duffel bag and also a book bag full of ammunition. On December 17, 2001, he was sentenced to 8 1/2 years.
17-year-old Joshua Magee was arrested in the parking lot of Malcolm High School after a school staff member, who saw the youth drinking liquor and putting on a black overcoat, called police. A search of Magee's car produced a bolt-action rifle, 20 bombs and a note stating the he wanted to injure everyone at the school except for three friends. Magee, to whom school paid close attention after it was reported to faculty that he was experimenting with explosives at home, was charged with attempted murder.
A 15-year-old boy from Monroe was already on juvenile probation when he broke down crying, police said Tuesday night, as he admitted he stockpiled bottles of gasoline, makeshift fuses, a torch, a 2-foot machete and three tanks of propane in a plot to attack former fellow students at Monroe-Woodbury High School.
Just because it involves a gun doesn't mean if you just see something that could be a bomb you don't do the same thing.
"Oh my god is that a bomb? Wait, I don't see a gun. He must be cool."
It's not bomb safety only if the guy has a gun too.
Maybe the guns are somewhere else. Maybe they're setting up the bomb now and getting the guns. Maybe it's an empty bomb and he's showing his friends before they fill it.
Just because the kid isn't waving an AK-47 around doesn't mean it's still can't be a credible threat.
