I, myself, as a dutch youth, have never encountered the mosquito (I live in a rural area). However, I am quite sure it IS unconstitutional. We have a Freedom-Of-Gathering constitution, which allows any group to form anywhere within the bounds of the law (In other words, if they don't go throwing rocks, 8 16-year olds may go anywhere as they please by the constituion) The mosquite prevents that from happening, thus, it is unconstitutional.
(And what is a mosquito doeing near a school? A mosquito is supposed to scare off kids, why do you want to scare people away from schools?)
