With each new development, TCU and Fort Worth are left wondering how their national reputations will be affected.

And now, Fort Worth is asking its residents to send a national message.  The city council has asked for residents to wear purple on Tuesday in a show of solidarity.

“If a family member has a tough time and they’re going through a bit of a struggle, the rest of the family jumps in and shows support. Well, TCU has been a long standing family member of this city,” said Fort Worth City Council member Dennis Shingleton.

Friday was campus visitation day at TCU. Parents from across the country, like Mary Bosch from San Diego, are in town to see TCU and decide whether they want to send their kids to school here.

Mary, like others, have been impressed with how both the city and school have handled the situation.   “We love the way the city supports the school and the school supports the city. Obviously they wouldn’t be supportive if it wasn’t a very good place.”

Even TCU’s most famous graduate chimed in.  CBS News Chief Washington Correspondent Bob Schieffer said he was proud of how the school has handled itself.

Back on campus, the optimism of moving beyond the drug arrests could be felt at the baseball team’s home opener at Brown-Lupton Stadium.

“This gives us something to rally behind and it shows that we are still a strong community,” said TCU Student Body President Brent Folan.

Folan says the student body is the process of coming up with policies of conduct for all students. They hope to have that up in the next few weeks.
