It's not inviting someone in, it's just bloody common sense. This isn't the 60's any more.
Nah your talking bollocks mate.
Sometimes I may be cleaning my cars, or working on them in my driveway, in which case the front door may be open.
Whether it's the 60s or not, it shouldn't be that people are scared sh!tless to hang out in their own property because of what can happen.
I can relate to this but still, in this video no one is on the drive and so I would keep the door locked.
They've obviously monitored the area, this is a very specific robbery, they knew what they were after. It all adds up, this isn't a spur of the moment thing.
