Improving Existing Code

Relativity's document processing service redacts flagged text from legal documents before they're produced to opposing counsel. Below is a review class one of your engineers submitted for the redaction batch job. How would you improve this piece of code?

public class DocumentRedactor
{
    private const string ConfigPath = "C:\\relativity\\config\\redaction-rules.json";

    public void RedactBatch(List<LegalDocument> documents)
    {
        foreach (var doc in documents)
        {
            try
            {
                var reader = new StreamReader(doc.FilePath);
                var text = reader.ReadToEnd();

                if (doc.Status == "Reviewed")
                {
                    continue;
                }

                var rules = LoadRules(ConfigPath);
                var redacted = ApplyRules(text, rules);

                File.WriteAllText(doc.FilePath, redacted);
                doc.Status = "Redacted";
            }
            catch (Exception)
            {
                continue;
            }

            int retries = 0;
            while (!VerifyRedaction(doc) && retries < 3)
            {
                Thread.Sleep(2000);
                retries++;
            }
        }
    }
}

Explain what you would improve and why, including any correctness risks given this handles sensitive legal documents.
