Do you really think a crazed 18 year old with limited combat experience, and I'm going to guess a less than optimal physical build, to do 15 to 20 double taps to the head in a room full of panicked teenagers, let alone do it fast enough so that he or she still has viable targets in the room after he/she has reloaded or switched weapons?
When you enter a classroom, you first shoot everyone once or twice in the torso, males and people close to exits first. If you use extra-high capacity magazines (like
this or
this), you may not have to reload at all. You can then either secure your victims with headshots, shooting
everyone, including the ones that look dead, or move onto the next classroom(s) and come back later to finish people off.
And you think that everyone's going to ignore the weapons and ammunition that are on this person when they are entering the building?
In most school shootings, the killer(s) had no problem entering the building. Handguns can easily be concealed, and rifles and shotguns can be carried in sports bags etc. Also, if anyone tries to stop you, you can simply
shoot them. Indeed, Eric & Dylan basically shot their way into the school, iirc.
You consider 32 deaths low, so I'm going to guess that you'd prefer a number like 60 or 70 at minimum to be acceptable. That would require 120 - 140 rounds of ammunition, assuming this person is a master sharpshooter and will never miss any shots.
No problem at all; Cho, for example, carried nineteen 10- and 15-round magazines, and almost 400 rounds of ammunition in his backpack. Spree killers usually have (much) more ammo with them than they actually use. Many even don't use all of their guns.
There's also the chance that one or more of these weapons will jam or malfunction during this time,
Yeah, that's why you should
always bring multiple weapons, for example a semi-automatic rifle (AR-15 with 150 round mag, plus additional 30 round ones) and 2 high capacity pistols (Glock 17c with 17/19 and 33 round mags).
that the psycho will not be able to dispatch of any police officers who are in the building, that someone will rush or sneak up on this person and that other enforcement will show up during this time.
Of course one should always choose a target that's relatively remote, or at least not near a police station. There are also various other measures one could take to delay the arrival of law enforcement, like creating a diversion with real or fake bombs, blocking the main access road(s) with trees and such, and chaining the main entrance doors of the target building shut (as Cho did; this will both keep targets in, and cops out). Also, once the police do arrive, you may be able to keep them at bay for a while with a scoped rifle.
Re being rushed or sneaked by intended victims: one should always initially position oneself in a corner away from the door(s), with a good view of the whole room. First shoot the men, then the women. Always have a backup gun holstered & ready within easy reach in case your main weapon jams, or there's no time to reload.
So you already admit that (1) you need more than one headshot and (2) special bullets.
Not exactly 'easy' considering that the legalised murderers all tend to aim for 'center mass' (ie : your body) instead of a small target like a persons' head.
Hollowpoints are a very common type of ammo, and as mentioned above, you first shoot people in the torso so they go down, and
then secure them with headshots.
So you expect mere crazy students to have decent weapons and ammo (even though anything remotely lethal can't be bought) and have practiced enough for them to be able to hit such targets ?
A Glock 17 or Beretta 92 with hollowpoints is pretty lethal, and can bought in most gun stores. If you (or your parents) own the guns legally, you can practice at a shooting range. Otherwise you can practice in some remote location, as Eric and Dylan did.
lucky for most of us then that most murderers don't use common sense
Indeed...
