Lock your car before open your gate

There was a crime happen in my neighborhood. It goes like this. There were a gang of 6 thugs waited outside the victim's house and they have plotted a plan to hijack the victim's car (of course, it's an expensive one). They were there early in the morning because they knew the victim will go to work at specific hour where nobody will be around.

Unfortunately, the victim changed his plan on that day and thugs were uneasy because it's going to be daylight. One of thug rode his motorcycle to the back of the house to check out if there are any ways to get into the house. He was lucky because the house owner's maid open the back door for some daily chores. He took this opportunity leap over the fence and charge into the house. Then, he threaten the family to be quiet or he will kill them.

Luckily, they all were at their room upstairs and one of them call the police. Nobody knows what happened to the thug downstairs as he left quickly after he can't find the car key (That's what we believe he's trying to find).

Here is the weirdest part. After he left the house, he and his gang went to a nearby house and tried to run down the gate (Perhaps they were angry when their plan has failed). One of them manage to get into the front yard of the house and the owner screamed after she saw what they're doing. Her scream shocked the thug and they left quickly afterward as they knew the police are coming.

After all these, I have came out some measures.

1. Don't buy expensive car and live in a neighborhood that the car doesn't seems to fit. (If you have a Benz, you should live in a neighborhood where there's a lot of Benz. Go figure.)
2. Keep a close eyes on the street before leaving the house. (Any suspicious person waiting outside? Ask your family to accompany you with an umbrella or better, a baseball bat)
3. Have your family member to open the gate for you. Wake them up and tell them about Point 2 if you sees one. Let them close the gate for you rather than leave the car engine running and close the gate by yourself.
4. Lock the car once you're in it. (The most basic of all)

I hope this will help. Please do leave any comments if there are some points I have missed.
