Depends on several factors. I sleep nicely with one on my door. Defeating the bar would make more noise and take longer than a perp would get once I wake up. And you assume the pepr would know what is impeding the opening of the door and patiently go find a yardstick/ As to the kids using it to keep a parent out, well even defeating it with a yardstick would teach a lesson don’tchaknow. [Drilling a small hole int he floor through which a 3” screw is inserted to hold the bar in place makes a yardstick just ridiculous.
I meant mostly to defeat the kids. But that’s a two way street. If they don’t have a kitchen and bathroom, you win by attrition. I’ve always had dogs...don’t need anything else...and I’d sure hate to get up in the middle of the night and step on that 3” screw.
