So I don't think #1 or #2 fit here....I guess it is just a matter of perception I don't see a problem with it and you do...I guess we can agree to disagree
So if your neighbor on the next block was arrested for having a meth lab you think it's OK for your house to be searched for a meth lab. Since he is doing it, you must be considered as possibly doing so as well. (definition 1)
And since every house in your neighborhood is searched at will for meth, that makes it OK. (definition 2)
So at what point do you think it does become 'unreasonable'?
