Trust a Texas National Security Investigations Lawyer Who Understands Your Rights

Do not talk to federal agents without a lawyer: Making false statements is a federal crime.

Suppose you are under investigation for providing material support to a foreign terrorist organization or any national security-related offense. In that case, speaking to FBI agents or federal investigators without legal counsel can lead to serious legal consequences.

Knowingly making a false statement (even if unintentional or based on a misunderstanding) can result in federal criminal charges punishable by up to five years in prison, or eight years in terrorism-related cases. Federal prosecutors frequently use information gathered during voluntary interviews as the basis for false statement indictments, even when no underlying terrorism or material support charges are filed. Before answering any questions, protect your rights and your future by contacting an experienced federal criminal defense attorney with a proven track record in national security and terrorism investigations.

Houston Defense Attorney John T. Floyd Law Firm: The Defense You Need during Your National Security Investigation

National security investigations are among the most serious legal challenges anyone can face. When federal agencies like the FBI, DHS, or the Department of Justice turn their attention toward you (whether for alleged espionage, material support of terrorism, foreign agent activity, or related offenses) the stakes could not be higher. These investigations often begin quietly, with surveillance, secret subpoenas, or seemingly routine interview requests, long before any charges are filed. And by the time you realize the full weight of the federal government is bearing down on you, critical decisions have already been made.

John T. Floyd and his team understand exactly how national security cases work and what it takes to fight back. With decades of experience handling complex federal cases, Mr. Floyd knows the tactics federal agencies use, how to challenge evidence obtained through classified proceedings, and how to protect your constitutional rights at every stage of the process: from the first signs of investigation through trial. He also knows that in these cases, silence and speed are your greatest assets. What you say, and when, can make all the difference.

When you hire The John T. Floyd Law Firm, you get a seasoned legal team that will evaluate the government’s case, handle all communications with federal investigators on your behalf, and build an aggressive, strategic defense tailored to the unique demands of national security law.

FAQ

What should I do if the FBI wants to talk to me?

K

L

Don’t answer any questions without a lawyer. Even if you haven't done anything wrong, talking to federal agents is very risky. Under federal law, making a mistake or saying something that could be misinterpreted can be considered a crime. Politely tell them you would like your lawyer present before speaking.

What is considered "aiding" a terrorist group?

K

L

The legal definition of aiding or providing "material support" is extremely broad. It’s not limited to giving someone weapons or money. The government states that providing a prohibited group with lodging, transportation, or advice of any kind is a violation of the law.

How severe are the penalties for these crimes?

K

L

The penalties are extremely severe. If convicted, you face:

Prison: 15 to 20 years in federal prison, or life imprisonment if someone dies.
Fines: Up to $1 million for businesses or individuals.

What are government "blacklists"?

K

The U.S. government maintains official, constantly updated lists of individuals, companies, and organizations banned worldwide. These include known terrorist groups and individuals accused of funding illegal activities.
