The radio buzz... the top talk radio stories of the day...

Ready, set - DEPLOY!

President Obama is sending 1,200 National Guard troops to boost security along the US - Mexico border.

What do the "experts" think:

WXNT Indianapolis, IN asked Ret'd Lt. Col. Jeff Addicott  - director for the Center for Terrorism Law at St. Mary's University - if sending these troops will make a dent in the problem...

Vice President for Homeland Security at the National Graduate School - Dr. David McIntyre - echoed a similar sentiment to Jamie Allman at KFTK St. Louis:

There's some concern in the law enforcement community that President Obama will repeat a move made by his predecessor - limiting the troops to support roles - instead of allowing them to make arrests and confront smugglers along the border.

Also making for some buzz today:

It's go time - BP shooting the "KILL SHOT" -- thick, dense mud - into the leaking pipe.

This being done in hopes of FINALLY plugging the oil leak that's been pumping oil into the gulf for over a month now.

Well - what are the odds it'll work?

Fox News Radio's TODD STARNES speaking with KTRH Houston, TX.

...if today's move doesn't work - there's a possibility of it making the leak WORSE.
