Sense Sonnet - Tickler

Touchy Solution

On the border with Mexico,
A cheap and simple fence be built,
Then keep it sprayed with goops that glow
On the skin of touchers with guilt
Of line crossing illegally.
As the naughty touchers proceed
Into U.S. territory.
Their colored skin will show their deed,
And law enforcement can detain,
And send the touchers back whence came.
And the touchers will touch again,
Around and round all play the game.

Avoid all the profiling stink.
Just look for those with hands bright pink.
