Harvard Law dropout raises $6M for Blue Voice to build a “Harvey for police officers”
David Lawrence, who dropped out of Harvard Law after an on-campus shooting involving a police officer, has raised $6 million to launch Blue Voice out of stealth, a Boston-based AI startup that gives police officers real-time guidance on department policy and law while in the field. The tool aims to address the fact that officers often make split-second decisions based on memory of thousands of pages of rules, protocols and local ordinances, with existing options—consulting a lengthy manual, waking a supervisor, or using generic AI tools prone to errors—proving too slow or unreliable.
The funding round was led by SignalFire and Las Olas VC, and Blue Voice is co-founded by Lawrence alongside Amit Patankar, a former Google engineer, and Michael Gropman, a retired Boston police deputy chief. The platform, likened to legal AI tool Harvey, is now used daily by officers at 225 county agencies across 25 states, with the customer base growing elevenfold over the past year; it answers a question roughly every minute and points officers to original regulations rather than generating standalone answers. Lawrence cites examples including a rookie officer using the app to confirm grounds to intervene in a suspected child enticement case, and hopes the tool shows that AI can improve public safety without compromising civil rights, at a time when police AI use, such as Flock Safety's surveillance systems, faces growing scrutiny.

Police officers are expected to follow laws and department rules that can vary between places and run to many pages. In the field, they may have little time to check them, so they can rely on memory or ask a supervisor.
Blue Voice is a US company developing an AI tool that lets officers look up policy and legal guidance while working. It was founded by David Lawrence, Amit Patankar, a former Google engineer, and Michael Gropman, a retired Boston police deputy chief.
The wider debate is about how AI might support public services while protecting people’s rights. Police use of technology is drawing scrutiny, so questions include whether such tools give reliable guidance, how officers use it, and how their decisions are overseen.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Police officers must make consequential decisions quickly while navigating complex, changing rules, and a reliable tool that surfaces relevant policy and cites its sources could help them act lawfully and consistently. Supporters may see this as a practical aid to public safety and civil rights, especially if it helps less experienced officers check their authority instead of relying on memory or generic AI.
The case against
Even a well-sourced tool could misstate or omit a rule, and officers under pressure may place too much trust in its guidance when decisions affect people’s rights and safety. Critics may argue that AI in policing needs rigorous independent testing, clear accountability and safeguards against misuse; adoption across many agencies does not by itself show that the system is accurate or that it improves outcomes.
