Past professors, ballistics & DNA experts testify in Zimmerman trial Wednesday

The George Zimmerman murder trial takes a break today for the July Fourth holiday.

But prosecutors are expected to wrap up their side of the case when court resumes on Friday.

They spent Wednesday trying to paint a picture of Zimmerman as a well-educated police officer wanna-be.

CNN's George Howell reports the details from Sanford, Florida.

“Zimmerman's past could haunt him if jurors are swayed by the picture prosecutors are trying to paint,” Howell reports, “a ‘wanna-be’ cop, who went too far, then less than forth-coming about how well he knew the law–-on national TV.”
