Konrad Lorenz tells us that "man is not a killer, but the group is." Shalit
demonstrates a profound understanding of this process and has researched it
extensively: All crowding has an intensifying effect. If aggression exists,
it will become more so as a result of crowding; if joy exists, it will
become intensified by the crowd. It has been shown by some studies ... that
a mirror in front of an aggressor tends to increase his aggression if he
was disposed to be aggressive. However, if this individual were not so
disposed, the effect of the mirror would be to further enhance his
nonaggressive tendencies. The effect of the crowd seems to be much like a
mirror, reflecting each individual's behavior in those around him and thus
intensifying the existing pattern of behavior. Lt. Col. Dave Grossman, On
