And yes all of them are part of the overall plan which is why it’s called “border security” and not just “border wall”. And you can “feel” however you want to I suppose but feelings aren’t reality. 30’ is tall, really tall, no one is vaulting over that. No one is cutting through it in 30 seconds, or even 30 minutes, if it is properly designed and built properly.
It will be very effective as part of an overall border security design.
