If you're in an argument with somebody and they get in your face and then look away, there's a good chance they're about to try and knock your head off

Look both ways crossing a one way street.... there may always be one idiot

Never talk money on public transportation, and never count money in a parking lot.

Trust your gut. You see people acting normally your whole life. You know what it looks like. If you see something that makes you uncomfortable, there’s a reason, even if you don’t know what it is yet.

If it sounds too good to be true, it probably is.

My dad preached "Focus sound more than any other sense. Your eyes can only see a 180°, your ears can see 360°." Saved my life more than once!!

Teach your kids how to effectively draw attention to themselves if they are in danger. A screaming child gets nobody's attention. I was taught, if a stranger ever grabbed me, to scream at the top of my lungs, "LET GO OF ME! I DO NOT KNOW YOU!"

You don't owe anybody anything, including conversation. People who want to take advantage of you will usually start by initiating unsolicited conversation.

Don't post location photos until you return home. People shouldn't know when your house is empty.

Look like you know where you are going even when you don't. If you have any misgivings about a particular street or area, go with it. If you do have to walk through an area where you are being scoped acting like you are insane and barely keeping it in makes you not worth the trouble. Don't worry about being polite if approached but don't be an a-hole. If an area smells like piss no one gives a f**k what happens there. Never fall for the I need 20 bucks for sick kid/locksmith/medicine/tow truck scam. Never pull out your money or wallet to check it. Even if you put it back they will know where it is. If you get bumped and feel for your wallet its also a cue for a pickpocket. Use reflections in windows to see behind you and possibly around a corner. I'm glad I grew up in a big city. Travelling around the world was much easier than for others I've seen.

Don’t use the top blanket in a hotel bed. We don’t wash them very often

Pay attention to the ppl at parties who are not drinking.

Never underestimate anybody, and i mean both ways, good and bad.

Women. Don't be afraid of being impolite if you feel threatened. Don't think "oh no I might hurt his feelings" or "well that one time I was told I over react so maybe this is another one of those times". No. If someone isnt a pos they will realize that the situation was misinterpreted. If they're a rapist murderer, they will most likely make a big deal about how they're not going to hurt you. Don't be afraid to make a scene if you're afraid.

If you need to scream for help, don’t yell HELP! Yell FIRE! Instead. Not all people who hear a yell for help will think it’s genuine, or they don’t want to get involved. When you yell fire, everyone wants to get out of the building in case theirs is the one on fire.

People make pickpockets' livelihood so easy. Just check out how many phones are in people's back pockets, how many handbags dangle by the side, easily accessible. Always put valuables in an inside, preferably zipped pocket. If you in a notorious pickpocket area like Paris or Naples, you can even carry a fake wallet with monopoly money in an outside pocket.

Pretend to be crazy, talk to yourself and swear loudly, no one knows how to handle crazy.

If you think that someone is looking at you, look at another direction and if they look in the same direction, they were looking at you.

Act like you're in a hurry and less people will want to bother you.

I dunno if this is street smarts but so many people lack situational awareness. By that I mean they are not being fully aware of their surroundings. Which has been made even worse with phones and headphones. If you sense anything dodgy trust that instinct and do something about it. I’d rather cross the street and look paranoid that get mugged. Or even just run. This group of guys were following close behind me when I was walking home from the pub alone. They could have just been walking the same way but as soon as I hit a corner I sprinted a hundred metres or so and didn’t see them again. I don’t care how strong you are you are losing 99% of the time versus 3 people.

Look both ways before coming out of a doorway if you think you're in a bad neighborhood. Think you're being followed? Go down the block, make a left. Make a left. Make a left. You eventually come full circle. If the same person is behind you, you're definitely being followed. Be confident and walk tall. Bad guys typically try to pick on the weak. Typically if you're not scared, they think there's a good reason for that, ie. packing heat.

Aimless people are generally up to no good. If you see a person walking around like they don't have a destination or they are looking around like they don't know what to do with themselves it means they are planning on jumping someone. They are trying to seem non threatening while at the same time scouting for victims. They are hoping some poor oblivious person lets them get too close. The best case is they are planning to pick pocket someone. The worst case is a violent mugging. If you see someone like this don't get near them and definitely don't take your eyes off them. Often just staring at them is enough to discourage them because they are cowards looking for easy prey and they don't want to be identified later.
