Dushan,
No the reason they get longer is because every time some one in the TSA reads another novel they add to the security procedures.!
Like removing shoes, belts, computers, metal reinforced bras, watches, tiepins etc !!
Arriving from Europe to Atlanta you even have to go through this AGAIN just to ride the transit bus to collect your baggage !
Mind you they still ask you that all important and fiendishly probing question
" Do you have anything in your baggage that could be used as a weapon"
Freud eat your heart out
