I agree that there are more instances of BnE during the day light hours. This is because most instances are for stealing purposes. Therefore the intruders work while no one is at home. Most instances where intruders intend to do bodily harm, kidnapping, etc... occur at night usually between midnight and 0200.
In the daytime scenario against the average thief, just your presence alone will cause the intruder to leave. Not saying everytime so don't everyone jump me...but in most cases yes.
Wherein, the night time intruder is far more likely to put you in a situation to where you will legitimately have to "defend" your home and family.
Out of respect for all of you that wish to ban firearms...I promise to not use mine in your defense
