... however I do find the placement of the Teargas nozzels a little worrysome.....
Other than the obvious sexual innuendo,
the gas jets do make some sense. They appear to be at about eye level to the target so would be immediately effective on the first few rows of any mob. (Dangerously so, maybe, because having gas directly enter the eyes under high pressure would probably result in some major damage. In most cases, tear gas is seen rising upwards as a thin, relatively speaking, cloud, from a canister thrown, or fired, on the ground.)
