No, it shouldn’t be illegal. Burglary and home invasion should be illegal … oh wait. THEY ARE!
How many houses are burgled by people who politely come to the door and ring the bell? How common are “home invasions?” Statistics please… betting that the last thing that most burglars want to deal with is an irate homeowner, possibly holding a weapon.
It’s your right not to answer the door, or even disconnect the doorbell. But it’s disgusting that you support making something illegal just because of your personal preferences and fears. While I agree with a lot of what you say, your “law and order” attitude is frankly nausea-inducing.
No, there oughtn’t be a law, generally speaking. And I’d NEVER call the cops on someone who knocks on my door and offers a service. There’s no worse type of human being in my book than a do-gooder snitch who rats on people who aren’t actually hurting anyone, even if they’re technically breaking some asinine law or other.
Burglary in progress? Violent crime? You bet I’d call the cops. But not for a couple kids going door to door trying to make a few shekels. Anyone who works independently rather than (say) at some crummy fast-food joint for a multinational mega corp should be applauded, not arrested.
