What points were ignored? 10 times as many border guards are required without a fence than with a fence. The fence makes guarding the border cheaper. All those against building a fence are actually against sealing the border. They support illegal immigration.
You aren't fooling anyone.
Why are 10 times as many guards needed?
A fence would have little impact on the number of people required to seal the border.
1/10th the guards are needed. The fence reduces the number of personnel needed to control the border. Only lying pieces of shit would claim otherwise.
Based on?
You are making bald faced statements without a single shred of logic or evidence to back it up and then claling people 'lying pieces of shit.' That does not make a reasonable argument at all. Simply stating it does not make it fact.
FACT: you need people at the fence to stop those climbing over, cutting through or digging under.
Now ask yourself this:if it takes two people to patrol X feet/miles of open terrain with sensor nets telling you exactly where they are, what - PRECISELY - does the fence change? Why can one person now patrol 2X land where the sensor net only allows X?
The answer is, of course, nothing. The fence essentially fills two roles on the border - slows them down while they are cutting through it/climbing over it and places a clear line where they are not supposed to go. You still require the same number of personnel to go and actually apprehend those crossing. Without those personnel, people will cross with little to no hindrance.
We may need to fill in gaps in the sensor network (I do not believe that it is complete) but it would be irrelevant to do so (or build a fence) without the proper personnel manning the fence to apprehend those that are crossing over.
