Tampering with a witness, victim, or informant violates Florida Statute § 907.041. Using intimidation or force against a witness is a third-degree felony, while the "anti-bail" provision — discouraging a victim from pursuing prosecution or appearing in court — is a first-degree misdemeanor for a first offense and a third-degree felony with a prior. Because the statute reaches casual phone calls and texts, defenses focus on the content and context of communications, lack of corrupt intent, and constitutional overbreadth arguments.
