<p>Certainly New Haven has more than its share of “murderous homeless guys”, as you put it, but this ought not be a problem as long as you act sensibly: </p>
<p>(1) never leave campus alone, if you can help it - particularly after dark; </p>
<p>(2) be aware at all times of the location for the nearest blue phone; and </p>
<p>(3) if anyone the least bit suspicious approaches you, scream just as loudly as you can - “police… POLICE!!” - and run back to your college, where the locked gates will keep you safe from most intruders. </p>
<p>(A tip: while you are running, drop your purse or wallet where your pursuer can see it. He may be satisfied to have your money and credit cards, and decide to spare you bodily harm.)</p>
