If you take a look at the page that says what character skills are implemented (fully, partially, not), it shows projectile weapons as partially implemented. But the sim news doesn't say they are implemented???.... Some others seem to be partially implemented too.
If you actually read a little further in the description you would find that said skills can have an effect on your chances of being arrested. So although you cannot technically shoot anyone yet, the skill can be used to escape arrest by 'shooting' at the arresting party.
