You agree you are more likely to get pulled over; late at night (when every one is asleep); because police are bored & have nothing to do?

I wake up real early in morning, like 5 am.  The streets are completely empty at this time.  I drive normally, sober, with seat belt on, and obey all traffic signs.  Yet, still:  Somehow I get pulled over easily driving at these hours.  One time:  Cops said they heard a woman scream in area I just came from.  Or:  Maybe I swung out too wide on another occasion on a right turn.  I come to realize there is no one on the streets at these hours but druggies, cops, etc.  Sometimes; I believe since there is no one on streets...I can just blow right through a stop sign after looking both ways.  After all:  Who am I going to hit?  So when I do this; or any little thing I do...here come the police with flashing lights and sirens...pulling me over to question me where I am going, and where I came from.   Also:  What I do for a living.  I do these same oversights during broad daylight with no police pulling me over.  Can someone help explain this.?
